1102-1104:Minor ยท Potential issue ยท Quick win
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.Probing an existing output is not protected against
MediaShrinkerError. A corrupt or empty existing file aborts conversion instead of being treated as an invalid output; the legacy-output probe has the same failure path.Every subsequent run fails on that file, including runs with
--overwrite, until the unusable output is manually removed.This can occur when: A previous interruption leaves a zero-byte or unprobeable canonical or legacy output under the size target.
audio_library.py: 1
2869-2870:Minor ยท Potential issue ยท Heavy lift
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.The whitelist still permits arbitrary local file access, so it may not prevent the LFI described as fixed in .jules/sentinel.md. A verified staged playlist could reference another readable local audio file.
Transcription could expose the private recording instead of only processing the verified staged artifact.
This can occur when: An attacker submits a playlist whose segment is an absolute path to a private WAV file readable by the FFmpeg process.
tests/test_audio_library.py: 1
4576-4576:Minor ยท Potential issue ยท Quick win
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.This descriptor-input assertion checks the input position but not the whitelist value. The unbounded non-descriptor invocation also does not assert that value.
This test can pass even though ordinary and descriptor-bound decoding permit network protocols.
This can occur when: A regression adds http and tcp to the whitelist only when start_seconds is absent, while retaining the same argument positions.
