CVE-2026-114050

Name of the Vulnerable Software and Affected Versions vLLM versions prior to 0.31.0

Description The software uses a client-supplied multimodal uuid verbatim as a cache identity without performing consistency checks on cache hits. This allows unauthenticated attackers to desynchronize the P0/P1 processor caches, triggering a fatal token-placeholder mismatch that crashes the entire serving instance, requiring a restart to recover.

Recommendations Update to version 0.31.0 or later.
