{"id":"CVE-2026-42208","aliases":["GHSA-r75f-5x8p-qvmc","PYSEC-2026-391"],"url":"https://o3.security/vulnerability/CVE-2026-42208","summary":"LiteLLM: SQL injection in Proxy API key verification","details":"### Impact\n\nA database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted `Authorization` header to any LLM API route (for example `POST /chat/completions`) and reach this query through the proxy's error-handling path.\n\nAn attacker could read data from the proxy's database and may be able to modify it, leading to unauthorised access to the proxy and the credentials it manages.\n\n### Patches\n\nFixed in **`1.83.7`**. The caller-supplied value is now always passed to the database as a separate parameter. Upgrade to `1.83.7` or later.\n\n### Workarounds\n\nIf upgrading is not immediately possible, set `disable_error_logs: true` under `general_settings`. This removes the path through which unauthenticated input reaches the vulnerable query.\n\n### References\n\n- Patched release: [`v1.83.7-stable`](https://github.com/BerriAI/litellm/releases/tag/v1.83.7-stable)\n\n**Discovery Credit**: Tencent YunDing Security Lab","published":"2026-05-08T03:38:14.124Z","modified":"2026-10-21T02:52:34.488480791Z","cvss":null,"epss":{"score":0.8942,"percentile":0.99777,"asOf":"2026-09-17"},"cisaKev":{"dateAdded":"2026-05-08","dueDate":"2026-05-11","knownRansomwareCampaignUse":false},"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"litellm","fixedVersion":"1.83.7"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/BerriAI/litellm/releases/tag/v1.83.7-stable"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-42208.json"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-42208"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-42208"},{"type":"ADVISORY","url":"https://github.com/BerriAI/litellm/security/advisories/GHSA-r75f-5x8p-qvmc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42208.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42208"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2463965"},{"type":"PACKAGE","url":"https://github.com/BerriAI/litellm"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-r75f-5x8p-qvmc"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/litellm/PYSEC-2026-391.yaml"},{"type":"WEB","url":"https://pypi.org/project/litellm"}],"provenance":{"sources":["OSV.dev","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:52:34.488480791Z"}}
