RIFF/FORM alone are generic container markers; verify the audio sub-type.
RIFF (Line 11) also identifies AVI and WebP, and FORM (Line 24) is the generic IFF chunk used by many non-audio formats. Matching only these 4 bytes at offset 0 lets non-audio containers pass the check, which undercuts the goal of this PR. WAV requires WAVE and AIFF requires AIFF at offset 8. The current single {offset, bytes} + .some model can't enforce a compound match, so the table needs a small reshape to require both parts.

Could a maintainer please add the 'nsoc26' label to this PR? This contribution is part of the NSOC 2026 program and implements magic byte validation to ensure audio files are legitimate before processing. |
The voiceController.cloneVoice handler now validates uploaded audio buffers against known magic-byte signatures before accepting them (see: isValidAudioBuffer). This prevents arbitrary binary data from being forwarded to ElevenLabs. The tests were still using a dummy "fake-audio" buffer that failed validation. Updated both mock-mode tests to use WebM magic bytes (0x1A 0x45 0xDF 0xA3) followed by padding so the validation passes and the tests can verify the handlers work correctly in mock mode.

Implementation ReviewThe audio magic bytes validation is a strong security improvement — it prevents MIME-type spoofing attacks where an attacker uploads a malicious file labeled as audio. The implementation correctly validates the file signature before processing. Recommendation: Resolve the merge conflict with main, and this PR should be ready. The audio validation logic is solid and complements the existing cloning flow. Please consider adding the Thank you! |

📝 Description
The
/api/voice/cloneupload path accepted any file whoseContent-Typeheader started with
audio/. That header is supplied by the client and canbe trivially spoofed, so arbitrary binary data could be buffered in memory
and forwarded to ElevenLabs as reference audio. This adds a content-based
check that verifies the uploaded bytes actually begin with a known audio
format signature before the file is accepted.
