cmcp 0.7.1

Three security fixes, backported onto 0.7.0 so they ship without the breaking Agent Manifest binding change and the opaque provider removal waiting on main. Full detail in CHANGELOG.

• GHSA-frxc-7f57-6f4r: deny a Cedar Allow that comes with evaluation errors, instead of skipping the errored policy and allowing.
• GHSA-mrcx-xvv4-m7f8: bound the TPM AIA certificate fetch. Each hop resolves the host once, connects only to that checked address, and the hop and byte limits hold.
• GHSA-2p85-666x-xm7x: classify upstream drift against the drifted tool's own catalog entry.

SDK on PyPI as cmcp-runtime 0.7.1.

[0.7.1] - 2026-10-19

Security

• A Cedar Allow reached with evaluation errors was enforced as Allow (GHSA-frxc-7f57-6f4r). Cedar skips a policy whose condition errors, so a forbid reading a context attribute the current phase does not carry could not stop a matching permit. CedarBackend now denies any Allow that comes with evaluation errors, and the error reaches the tool_call or egress_denied audit row. So that a policy written for one phase does not deny in the other, both phases now carry the same context keys: egress adds session_max_sensitivity (the label string), arguments, baa_covered, compliance_domain, server_identity, destination_class and attestation_platform, and ingress adds egress (false), sensitivity_level, injection_events, reset_count and response_size_bytes (0). Without this the shipped BFSi demo denied every response at egress. A policy that reads a key outside that set, or workflow_id when the caller declared none, now denies.
• The TPM AIA certificate fetch was unbounded (GHSA-mrcx-xvv4-m7f8). The chain walk followed redirects to any address and read responses without a limit. It now refuses destinations that do not resolve to global addresses, checks every redirect the same way, follows at most three and ignores responses over 64 KiB. Each hop's host is resolved once and the connection goes to the checked address (the request still names the host, and HTTPS still verifies the certificate against it), so a second DNS answer cannot point the fetch somewhere else. The fetch no longer uses environment proxies. An on-prem CA whose AIA host has a private address falls back to the vendored bundle.
• Upstream drift was classified against the wrong catalog entry (GHSA-2p85-666x-xm7x). The scanner received the server of whichever entry was last in the catalog. Detection and fail-closed denial were not affected; only the classification written to the audit row was.

Updates pytest from 9.1.1 to 9.2.0

Release notes

Sourced from pytest's releases.

9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.

Updates starlette from 1.7.0 to 1.10.0

Release notes

Sourced from starlette's releases.

Version 1.10.0

📝 Leaner URL-encoded form parsing

Starlette 1.10.0 parses URL-encoded forms with less memory and CPU, no longer drops the last field when a stream ends early, and lets you compare FormData that holds several uploads under one key.

uv pip install starlette==1.10.0

• Forms with many fields parse faster and use less memory (#3724). FormParser builds each field in the parser callbacks instead of queueing every event and replaying it. On CodSpeed, 1000 fields went from 42.8 ms to 34.9 ms and from 63.5 KB to 54.5 KB, and the max_fields limit case went from 6,880 B to 864 B.
• The last field is kept when the request stream ends without an empty chunk (#3599). The parser is now finalized once the stream is exhausted, so custom streams that never yield a final b"" no longer lose their last field.
• FormData with repeated uploads can be compared (#3619). Comparing two FormData objects with several UploadFile values under the same key used to raise TypeError.

⚠️ Behaviour changes

• Multidict equality keeps the order of values under a repeated key (#3619). Keys can still appear in any order, but QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal, matching what getlist() returns.
• starlette.formparsers.FormMessage is deprecated (#3724). The parser no longer uses it, and FormParser.messages is gone. Calling FormMessage(...) emits a StarletteDeprecationWarning.

🧭 Routing and URL generation

• Path parameter values that look like a placeholder are kept as they are (#3725). url_path_for("route", category="{id}", id="42") on /{category}/{id} now returns /{id}/42 instead of /42/42. Substitution also got faster, from 549 ns to 520 ns with two parameters and from 1,078 ns to 779 ns with five.
• Route matching does less work per request (#3665, #3722). Match members are compared by identity, cutting up to 4.9% of the instructions per dispatch in the routing benchmarks.
• WSGIMiddleware strips root_path only at a path segment boundary (#3718). A request to /application under a root_path of /app no longer becomes /lication.
• FloatConvertor reports NaN and infinity correctly (#3716). NaN was reported as a negative float.

🛡️ Middleware, responses and config

• Handled exceptions no longer keep requests alive (#3205). Starlette clears the traceback after an exception handler runs, so an exception instance reused across requests, such as a module-level HTTPException, no longer pins per-request objects in memory.
• Middlewares accept http.response.start without headers (#3721). BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware default the omitted field to an empty list instead of raising KeyError.
• FileResponse ignores Range on methods other than GET and HEAD (#3679). A POST endpoint that returns a file now sends the full file, as RFC 9110 requires.
• Config strips one pair of matching outer quotes from env file values (#3720). KEY='say "hi"' now reads as say "hi" instead of say "hi.

Full changelog: 1.9.0...1.10.0

Version 1.9.0

This release streams TestClient response bodies, so client.stream() returns before the application finishes. It also escapes path delimiters when building URLs, matches host names case-insensitively, and keeps every existing Vary header.

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

1.10.0 (October 24, 2026)

Changed

• Compare multidicts such as FormData and QueryParams by key while keeping the order of values under a repeated key, so FormData with repeated uploads no longer raises TypeError. QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal #3619.
• Build URL-encoded form fields in the parser callbacks, lowering memory and CPU usage for forms with many fields #3724.
• Compare Match members by identity during routing #3665 and #3722.

Deprecated

• Deprecate starlette.formparsers.FormMessage, which is no longer used #3724.

Fixed

• Parse the last URL-encoded form field when the request stream ends without an empty chunk #3599.
• Keep path parameter values that look like another placeholder in url_path_for() #3725.
• Default omitted http.response.start headers in BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware instead of raising KeyError #3721.
• Clear the traceback of handled exceptions, so reused exception instances no longer keep per-request objects alive #3205.
• Strip only one pair of matching outer quotes from Config env file values #3720.
• Strip root_path from PATH_INFO only at a path segment boundary in WSGIMiddleware #3718.
• Report NaN and infinity correctly in FloatConvertor.to_string() #3716.
• Ignore Range on requests other than GET and HEAD in FileResponse #3679.

1.9.0 (October 18, 2026)

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.

• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

1.8.0 (October 13, 2026)

This release drops Python 3.10 support and adds HTTP 103 Early Hints.

Added

• Add Request.send_early_hints() for HTTP 103 Early Hints through the ASGI http.response.early_hint extension #3435.

Changed

• Require Python 3.11 or later, dropping support for Python 3.10 #3592.
• Exclude native gRPC media types (application/grpc and application/grpc+...) from GZipMiddleware compression by default #3565.
• Send http.response.start immediately in GZipMiddleware for responses with an existing Content-Encoding, status 206, or an excluded content type, instead of waiting for the first body chunk #3631.

Updates cmcp-runtime from 0.7.0 to 0.7.1

Release notes

Sourced from cmcp-runtime's releases.

cmcp 0.7.1

Three security fixes, backported onto 0.7.0 so they ship without the breaking Agent Manifest binding change and the opaque provider removal waiting on main. Full detail in CHANGELOG.

• GHSA-frxc-7f57-6f4r: deny a Cedar Allow that comes with evaluation errors, instead of skipping the errored policy and allowing.
• GHSA-mrcx-xvv4-m7f8: bound the TPM AIA certificate fetch. Each hop resolves the host once, connects only to that checked address, and the hop and byte limits hold.
• GHSA-2p85-666x-xm7x: classify upstream drift against the drifted tool's own catalog entry.

SDK on PyPI as cmcp-runtime 0.7.1.

Changelog

Sourced from cmcp-runtime's changelog.

[0.7.1] - 2026-10-19

Security

• A Cedar Allow reached with evaluation errors was enforced as Allow (GHSA-frxc-7f57-6f4r). Cedar skips a policy whose condition errors, so a forbid reading a context attribute the current phase does not carry could not stop a matching permit. CedarBackend now denies any Allow that comes with evaluation errors, and the error reaches the tool_call or egress_denied audit row. So that a policy written for one phase does not deny in the other, both phases now carry the same context keys: egress adds session_max_sensitivity (the label string), arguments, baa_covered, compliance_domain, server_identity, destination_class and attestation_platform, and ingress adds egress (false), sensitivity_level, injection_events, reset_count and response_size_bytes (0). Without this the shipped BFSi demo denied every response at egress. A policy that reads a key outside that set, or workflow_id when the caller declared none, now denies.
• The TPM AIA certificate fetch was unbounded (GHSA-mrcx-xvv4-m7f8). The chain walk followed redirects to any address and read responses without a limit. It now refuses destinations that do not resolve to global addresses, checks every redirect the same way, follows at most three and ignores responses over 64 KiB. Each hop's host is resolved once and the connection goes to the checked address (the request still names the host, and HTTPS still verifies the certificate against it), so a second DNS answer cannot point the fetch somewhere else. The fetch no longer uses environment proxies. An on-prem CA whose AIA host has a private address falls back to the vendored bundle.
• Upstream drift was classified against the wrong catalog entry (GHSA-2p85-666x-xm7x). The scanner received the server of whichever entry was last in the catalog. Detection and fail-closed denial were not affected; only the classification written to the audit row was.

On CodSpeed, 1000 fields went from 42.8 ms to 34.9 ms and from 63.5 KB to 54.5 KB, and the max_fields limit case went from 6,880 B to 864 B.
• The last field is kept when the request stream ends without an empty chunk (#3599). The parser is now finalized once the stream is exhausted, so custom streams that never yield a final b"" no longer lose their last field.
• FormData with repeated uploads can be compared (#3619). Comparing two FormData objects with several UploadFile values under the same key used to raise TypeError.

⚠️ Behaviour changes

• Multidict equality keeps the order of values under a repeated key (#3619). Keys can still appear in any order, but QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal, matching what getlist() returns.
• starlette.formparsers.FormMessage is deprecated (#3724). The parser no longer uses it, and FormParser.messages is gone. Calling FormMessage(...) emits a StarletteDeprecationWarning.

🧭 Routing and URL generation

• Path parameter values that look like a placeholder are kept as they are (#3725). url_path_for("route", category="{id}", id="42") on /{category}/{id} now returns /{id}/42 instead of /42/42. Substitution also got faster, from 549 ns to 520 ns with two parameters and from 1,078 ns to 779 ns with five.
• Route matching does less work per request (#3665, #3722). Match members are compared by identity, cutting up to 4.9% of the instructions per dispatch in the routing benchmarks.
• WSGIMiddleware strips root_path only at a path segment boundary (#3718). A request to /application under a root_path of /app no longer becomes /lication.
• FloatConvertor reports NaN and infinity correctly (#3716). NaN was reported as a negative float.

🛡️ Middleware, responses and config

• Handled exceptions no longer keep requests alive (#3205). Starlette clears the traceback after an exception handler runs, so an exception instance reused across requests, such as a module-level HTTPException, no longer pins per-request objects in memory.
• Middlewares accept http.response.start without headers (#3721). BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware default the omitted field to an empty list instead of raising KeyError.
• FileResponse ignores Range on methods other than GET and HEAD (#3679). A POST endpoint that returns a file now sends the full file, as RFC 9110 requires.
• Config strips one pair of matching outer quotes from env file values (#3720). KEY='say "hi"' now reads as say "hi" instead of say "hi.

Full changelog: 1.9.0...1.10.0

Version 1.9.0

This release streams TestClient response bodies, so client.stream() returns before the application finishes. It also escapes path delimiters when building URLs, matches host names case-insensitively, and keeps every existing Vary header.

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

1.10.0 (October 24, 2026)

Changed

• Compare multidicts such as FormData and QueryParams by key while keeping the order of values under a repeated key, so FormData with repeated uploads no longer raises TypeError. QueryParams("a=1&a=2") and QueryParams("a=2&a=1") are no longer equal #3619.
• Build URL-encoded form fields in the parser callbacks, lowering memory and CPU usage for forms with many fields #3724.
• Compare Match members by identity during routing #3665 and #3722.

Deprecated

• Deprecate starlette.formparsers.FormMessage, which is no longer used #3724.

Fixed

• Parse the last URL-encoded form field when the request stream ends without an empty chunk #3599.
• Keep path parameter values that look like another placeholder in url_path_for() #3725.
• Default omitted http.response.start headers in BaseHTTPMiddleware, GZipMiddleware and SessionMiddleware instead of raising KeyError #3721.
• Clear the traceback of handled exceptions, so reused exception instances no longer keep per-request objects alive #3205.
• Strip only one pair of matching outer quotes from Config env file values #3720.
• Strip root_path from PATH_INFO only at a path segment boundary in WSGIMiddleware #3718.
• Report NaN and infinity correctly in FloatConvertor.to_string() #3716.
• Ignore Range on requests other than GET and HEAD in FileResponse #3679.
