  "title": "Privilege escalation through cryptographic key reuse in LiteLLM",
  "summary": "LiteLLM proxy releases from 1.87.0 until the applicable patched release can allow an authenticated internal user to obtain proxy-administrator privileges. An attacker with that access can execute commands through the MCP stdio capability. Releases 1.87.0 through 1.90.x are affected only when EXPERIMENTAL_UI_LOGIN is enabled; later affected releases are exposed in the default configuration.",
  "mitigation": "Upgrade LiteLLM to 1.100.4, 1.101.3, 1.102.2, 1.103.1, or 1.104.0rc2, as appropriate for the release line. Until upgrading, set EXPERIMENTAL_UI_LOGIN=false to disable the affected login path.",
