From 1.87.0 until 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2, the proxy reuses one cryptographic context for at-rest secrets and session tokens, allowing an authenticated internal user to have crafted metadata containing a forged administrator credential encrypted and returned by the API-key flow. Replaying that ciphertext as a bearer token causes the proxy to trust the forged proxy administrator identity, permitting administrative access and arbitrary commands through the MCP stdio endpoint. Versions 1.87.0 through 1.90.x require EXPERIMENTAL_UI_LOGIN to be enabled, while versions after 1.91.0 are exploitable in the default configuration. This issue was fixed in LiteLLM 1.100.4, 1.101.3, 1.102.2, 1.103.1, and 1.104.0-rc.2.","published_at":"2026-10-22T18:01:52.768000Z","last_modified_at":"2026-10-23T19:42:24.553000Z","cvss_v3_score":9.9,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-269","CWE-345","CWE-441"],"nvd_references":["https://github.com/BerriAI/litellm/security/advisories/GHSA-7hp6-4w63-5g45","https://github.com/BerriAI/litellm/commit/1d5fdc87fed66b49e1df8cf7d708ad93249eb7d0","https://github.com/BerriAI/litellm/commit/9161d7f9d6073603ba61ee4aa5e2c0ef5b37a81b","https://github.com/BerriAI/litellm/commit/9fa1a641119dd0d4fe43e93622eae5f482ceb63f","https://github.com/BerriAI/litellm/commit/a80eacacee118fbed54e3d98f239d17a63fac818","https://github.com/BerriAI/litellm/commit/f7cd90f09e9716652b38daec9f0640cdf49d582b","https://github.com/BerriAI/litellm/releases/tag/v1.100.4","https://github.com/BerriAI/litellm/releases/tag/v1.101.3","https://github.com/BerriAI/litellm/releases/tag/v1.102.2","https://github.com/BerriAI/litellm/releases/tag/v1.103.1","https://github.com/BerriAI/litellm/releases/tag/v1.104.0-rc.2"],"vuln_status":"Awaiting
