Vllm · Vllm · CVE-2026-93592
**Name of the Vulnerable Software and Affected Versions**
vLLM versions prior to 0.28.0
**Description**
The software fails to validate the lower bound of token IDs in the '/v1/embeddings' and '/pooling' endpoints. This allows unauthenticated attackers to crash the engine by submitting negative token IDs. A single request containing a negative token ID triggers a CUDA device-side assertion, which poisons the GPU context and causes all subsequent requests to fail until the process is restarted.
**Recommendations**
Update vLLM to version 0.28.0 or later.
Avoid submitting negative values to the token ID parameter in the '/v1/embeddings' and '/pooling' endpoints.
