Prior to 0.30.0, flash late-interaction scoring at the /score and /rerank endpoints derives each worker's query_key value from the caller-controlled X-Request-Id header. A concurrent request that reuses a victim's identifier can overwrite the cached query embedding so the victim's documents are scored against the attacker's query, and shared use counters can also cause a late-interaction cache-miss error. This issue is fixed in version 0.30.0.","state":0,"publishedAt":"2026-10-05T22:47:54.854+00:00","modifiedAt":"2026-10-06T17:55:21.295+00:00","affected":[{"ecosystem":"Vendor product","name":"vllm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vllm-project\",\n                    \"product\": \"vllm\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 030.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L","score":4.2,"severity":"MEDIUM"}],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-2phq-3phc-84px","https://github.com/vllm-project/vllm/pull/51445","https://github.com/vllm-project/vllm/commit/ee17d0d869203ef9a35ad73358a4987bba14b1fc","https://github.com/vllm-project/vllm/releases/tag/v0.30.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105755","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105755","identifiers":["CVE-2026-105755"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
