{"id":"GHSA-r75f-5x8p-qvmc","summary":"LiteLLM has 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","aliases":["CVE-2026-42208","PYSEC-2026-391"],"modified":"2026-09-10T03:51:02.984377704Z","published":"2026-04-24T16:17:07Z","database_specific":{"cwe_ids":["CWE-89"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-04-24T16:17:07Z","nvd_published_at":"2026-05-08T04:16:19Z"},"references":[{"type":"WEB","url":"https://github.com/BerriAI/litellm/security/advisories/GHSA-r75f-5x8p-qvmc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42208"},{"type":"PACKAGE","url":"https://github.com/BerriAI/litellm"},{"type":"WEB","url":"https://github.com/BerriAI/litellm/releases/tag/v1.83.7-stable"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-42208"}],"affected":[{"package":{"name":"litellm","ecosystem":"PyPI","purl":"pkg:pypi/litellm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.81.16"},{"fixed":"1.83.7"}]}],"versions":["1.81.16","1.82.0","1.82.1","1.82.2","1.82.3","1.82.4","1.82.5","1.82.6","1.83.0","1.83.1","1.83.2","1.83.3","1.83.4","1.83.5","1.83.6"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-r75f-5x8p-qvmc/GHSA-r75f-5x8p-qvmc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
