CVE-2026-100654

vLLM versions before 0.29.0 are vulnerable to a Denial of Service (DoS) attack. The issue arises because the POST /v1/completions and POST /v1/chat/completions endpoints accept user-controlled stop_token_ids but fail to verify if these IDs fall within the model's vocabulary/logits range. When min...

CVE-2026-93592

A flaw was found in vLLM. An unauthenticated attacker can exploit an input validation vulnerability by submitting negative token IDs to the /v1/embeddings and /pooling endpoints. This action triggers a CUDA device-side assertion, which poisons the GPU context and causes the engine to crash...

SUSE CVE-2026-93592

vLLM versions before 0.28.0 fail to validate the lower bound of token IDs in the /v1/embeddings and /pooling endpoints, allowing unauthenticated attackers to crash the engine by submitting negative token IDs. A single request with a negative token ID triggers a CUDA device-side assertion that...

PT-2026-95371

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....

CVE-2026-54234: Improper Input Validation

vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Prior to 0.24.0, a frontend-legal multi-request speculative decoding workload can cause the rejection sampler to produce a recovered token equal to the model vocabulary size boundary value, which is then convert...
