description

SGLang through 0.5.21 may consume excessive worker memory while handling large video inputs in Qwen-VL deployments. An attacker able to send video requests to the chat-completions API can cause service disruption, especially when requests are made concurrently.

mitigation

Restrict access to the chat-completions endpoint and disable or filter video inputs where they are not needed. Enforce upstream limits on uploaded video dimensions and size, and cap request concurrency until a patched SGLang release is available.

no
exploit
no
automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
