A proxy administrator, or another privileged caller with permission to test model connections, could cause LiteLLM to read files from the local filesystem via an `oidc/file/` reference.\n\nBecause exploitation requires privileged proxy access, this is treated as a defense-in-depth issue rather than a cross-tenant privilege bypass.\n\n### Patches\n\nThe issue is fixed in `1.83.10-stable`.\n\nLiteLLM recommend upgrading to `1.83.10-stable` or later.\n\n### Workarounds\n\nRestrict `/health/test_connection` access to trusted administrators only.","published":"2026-07-08T19:33:32.816Z","modified":"2026-10-21T02:30:34.281676243Z","cvss":null,"epss":{"score":0.00572,"percentile":0.45808,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"litellm","fixedVersion":"1.83.10"}],"fix":{"url":"https://github.com/BerriAI/litellm/pull/25592","label":"BerriAI/litellm#25592"},"references":[{"type":"WEB","url":"https://github.com/BerriAI/litellm/releases/tag/v1.83.10-stable"},{"type":"ADVISORY","url":"https://github.com/BerriAI/litellm/security/advisories/GHSA-4g5m-c9r5-49xf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59819.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59819"},{"type":"FIX","url":"https://github.com/BerriAI/litellm/pull/25592"},{"type":"PACKAGE","url":"https://github.com/BerriAI/litellm"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:30:34.281676243Z"}}
