vLLM before 0.31.0 Remote Engine Crash via Forged Multimodal UUID

Published Oct 21, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
vLLM before 0.31.0 uses a client-supplied multimodal uuid verbatim as cache identity with no consistency check on cache hits, allowing engine crashes. Unauthenticated attackers can desynchronize the P0/P1 processor caches to trigger a fatal token-placeholder mismatch, killing the entire serving instance until restarted.
