vLLM Audio Decompression Bomb Vulnerability Between Versions 0.19.0 and 0.24.0

Sources read

Source agreement

0/2

Evidence confidence

%37

Short explanation

vLLM from version 0.19.0 before 0.24.0 contains a decompression bomb vulnerability because the AudioMediaIO multimodal path calls load_audio without the max_duration_s decoded-duration limit. Authenticated attackers can exhaust server memory via /v1/chat/completions requests.

Why does it matter?

This vulnerability allows authenticated attackers to expand small compressed audio files into massive decoded PCM, exhausting server memory resources and causing denial of service conditions.

What should be done?

Follow vendor advisory guidance
Update to version 0.24.0 or later where unaffected

Show the technical text from the sources

vLLM from 0.19.0 before 0.24.0 contains a decompression bomb vulnerability because the AudioMediaIO multimodal path calls load_audio without the max_duration_s decoded-duration limit. Authenticated attackers can send small compressed audio via input_audio or audio_url in /v1/chat/completions requests that expands to huge decoded PCM, exhausting server memory.
