Prior to 0.28.0, the default mirrored multimodal LRU cache can commit a media hash in the frontend sender cache during multimodal rendering and before engine admission, while the engine receiver cache never receives the payload if that request is rejected. A later request reusing the same media hash causes MultiModalProcessorSenderCache to send no payload and MultiModalReceiverCache to reach an assertion with the message \"Expected a cached item,\" producing a shared-service availability failure. This issue is fixed in version 0.28.0.","state":0,"publishedAt":"2026-10-05T22:37:19.633+00:00","modifiedAt":"2026-10-06T13:23:03.982+00:00","affected":[{"ecosystem":"Vendor product","name":"vllm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vllm-project\",\n                    \"product\": \"vllm\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.28.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-ph3r-5jfg-f84f","https://github.com/vllm-project/vllm/pull/46747","https://github.com/vllm-project/vllm/pull/51897","https://github.com/vllm-project/vllm/commit/396204230423b7cc6798300926b8fa30190d26a9","https://github.com/vllm-project/vllm/releases/tag/v0.28.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105753","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105753","identifiers":["CVE-2026-105753"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
