CVE-2026-116175— vLLM 0.19.0 before 0.24.0 Audio Decompression Bomb DoS via Chat Completions

Quick assessment

Affected
vllm-project vllm
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

vLLM 在 0.19.0 至 0.24.0 版本之间存在解压缩炸弹漏洞。该漏洞源于 AudioMediaIO 多模态路径在调用 时，未对解码后的时长设置 限制。已认证的攻击者可通过 接口中的 或 参数，上传体积很小但压缩率极高的音频文件；这些文件在解码后会膨胀为巨大的 PCM 数据，从而耗尽服务器内存资源。

Vulnerability Title
vLLM 0.19.0 before 0.24.0 Audio Decompression Bomb DoS via Chat Completions
Source: CVE Program / CVE List V5
Vulnerability Description
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.
