Summary
Duplicate Advisory: vLLM vulnerable to remote denial of service through forged multimodal UUID cache desynchronization
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-p92p-rxj5-7p2x. This link is maintained to preserve external references.

Original 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.
