{"id":"CVE-2026-105754","summary":"vLLM: Scale-out disaggregated multimodal transport trusts caller-supplied features","details":"vLLM is an inference and serving engine for large language models. Prior to 0.30.0, the /inference/v1/generate endpoint in the disaggregated scale-out path accepts caller-supplied tensors in the features.kwargs_data field, cache identifiers in the features.mm_hashes field, ranges in the features.mm_placeholders field, and wire-selected multimodal field processors without rebinding them to the active model renderer contract. Forged grid geometry, field types, or non-positive placeholder lengths can terminate the shared EngineCore; when an attacker knows or can induce a victim's content hash, forged cache hashes can poison or retrieve cross-request encoder-cache state; and dropped sparse placeholder masks can alter replayed transport semantics. This issue is fixed in version 0.30.0.","aliases":["GHSA-ph72-cqr5-qpp7"],"modified":"2026-10-07T02:47:27.595729149Z","published":"2026-10-05T22:46:03.163Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1284","CWE-20","CWE-617","CWE-639","CWE-668","CWE-704"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105754.json"},"references":[{"type":"WEB","url":"https://github.com/vllm-project/vllm/releases/tag/v0.30.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105754.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-ph72-cqr5-qpp7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105754"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/1970f3ed4be7fa8620e4ddc4a12c36a8384cfc27"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/51898"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vllm-project/vllm","events":[{"introduced":"0"},{"fixed":"1970f3ed4be7fa8620e4ddc4a12c36a8384cfc27"},{"fixed":"9ed533eb4adfe48aef7e569a08daeccd2a773fed"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.30.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.30.0rc2","v0.30.0rc1","v0.29.1rc0","proto-v0.1.0","v0.28.1rc0","v0.27.2rc0","v0.26.1rc0","v0.25.0","v0.23.1rc0","v0.22.1rc0","v0.21.1rc0","v0.20.2rc0","v0.20.1rc0","v0.19.2rc0","v0.19.1rc0","v0.18.2rc0","v0.18.1rc0","v0.17.2rc0","v0.18.0rc0","v0.17.1rc0","v0.17.0rc0","v0.16.0rc1","v0.15.2rc0","v0.16.0rc0","v0.15.0rc1","v0.14.0rc1","v0.14.0rc0","v0.13.0rc1","v0.11.1","v0.11.1rc6","v0.11.1rc5","v0.11.1rc4","v0.11.1rc3","v0.11.1rc2","v0.11.1rc1","v0.11.1rc0","v0.11.0rc1","v0.10.2rc2","v0.10.2rc1","v0.10.1rc1","v0.10.0rc2","v0.10.0","v0.10.0rc1","v0.9.2rc1","v0.9.1rc2","v0.9.1","v0.9.1rc1","v0.9.0","v0.8.4","v0.8.3rc1","v0.8.2","v0.8.1","v0.8.0rc2","v0.8.0rc1","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.6.post1","v0.6.6","v0.6.5","v0.6.4.post1","v0.6.4","v0.6.3.post1","v0.6.3","v0.6.2","v0.6.1.post2","v0.6.1.post1","v0.6.1","v0.6.0","v0.5.5","v0.5.4","v0.5.3.post1","v0.5.3","v0.5.2","v0.5.1","v0.5.0.post1","v0.5.0","v0.4.3","v0.4.2","v0.4.1","v0.4.0.post1","v0.4.0","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","submission"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105754.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
