Detailsinfo

A vulnerability was found in vllm-project vLLM up to 0.30.x. It has been declared as critical. This vulnerability affects some unknown processing of the component Cache. The manipulation of the argument EXIF ImageID/cache_salt with an unknown input leads to a hash predictable salt vulnerability. The CWE definition for the vulnerability is CWE-760. The product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product uses a predictable salt as part of the input. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

vLLM before 0.31.0 contains a cache aliasing vulnerability that allows authenticated attackers to collide shared cache keys by supplying caller-controlled values such as EXIF ImageID or cache_salt. Attackers can set a UUID EXIF ImageID to receive another request's cached processed media, or match cache_salt to a LoRA name to reuse first-block KV state.

The advisory is available at github.com. This vulnerability was named CVE-2026-114054 since 10/20/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1110.002 by the MITRE ATT&CK project.
