  "title": "Audio decompression amplification in SGLang",
  "summary": "SGLang versions through 0.5.21 can consume excessive memory and CPU while decoding attacker-supplied compressed audio. A remote attacker who can submit audio through audio_url or audio_data may cause denial of service by triggering expansion into oversized decoded audio buffers.",
  "mitigation": "Restrict or disable untrusted audio_url and audio_data processing, and enforce decoded duration, sample-count, and memory limits before or during decoding. Run audio handling with resource limits and isolation until an upstream fixed release is available; no fixed version is recorded.",
