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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-617"],"references":["https://github.com/vllm-project/vllm/commit/396204230423b7cc6798300926b8fa30190d26a9","https://github.com/vllm-project/vllm/pull/46747","https://github.com/vllm-project/vllm/pull/51897","https://github.com/vllm-project/vllm/releases/tag/v0.28.0","https://github.com/vllm-project/vllm/security/advisories/GHSA-ph3r-5jfg-f84f"],"products":["vllm:vllm"],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105753","score":0.00427,"percentile":0.36708,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-ph3r-5jfg-f84f","url":"https://osv.dev/vulnerability/GHSA-ph3r-5jfg-f84f","summary":"vLLM: Mirrored multimodal IPC caches desync after a rejected request — a later request reusing the same media hash trips a receiver assertion in the engine core","modified":"2026-10-08T10:10:52.271975688Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.28.0"],"fixed":["0.28.0"]}]},{"id":"PYSEC-2026-4197","url":"https://osv.dev/vulnerability/PYSEC-2026-4197","summary":"","modified":"2026-10-08T10:00:02.854871518Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.28.0"],"fixed":["0.28.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
