{"id":"CVE-2026-27893","aliases":["GHSA-7972-pg2x-xr59","PYSEC-2026-2297"],"url":"https://o3.security/vulnerability/CVE-2026-27893","summary":"vLLM's hardcoded trust_remote_code=True in NemotronVL and KimiK25 bypasses user security opt-out","details":"vLLM is an inference and serving engine for large language models (LLMs). Starting in version 0.10.1 and prior to version 0.18.0, two model implementation files hardcode `trust_remote_code=True` when loading sub-components, bypassing the user's explicit `--trust-remote-code=False` security opt-out. This enables remote code execution via malicious model repositories even when the user has explicitly disabled remote code trust. Version 0.18.0 patches the issue.","published":"2026-03-26T23:56:53.579Z","modified":"2026-08-07T11:50:43.571844720Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"vllm","fixedVersion":"0.18.0"}],"fix":{"url":"https://github.com/vllm-project/vllm/commit/00bd08edeee5dd4d4c13277c0114a464011acf72","label":"vllm-project/vllm@00bd08e"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-27893.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10140"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:10141"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19712"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19724"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19725"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:24977"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:37275"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:42644"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:8746"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:8747"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:8748"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-27893"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27893.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-7972-pg2x-xr59"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27893"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2452055"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/00bd08edeee5dd4d4c13277c0114a464011acf72"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/36192"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:43.571844720Z"}}
