CVSS 9.3 CriticalCriticalIn CISA KEVEPSS 0.89 · 99th percentile

Critical, because:

  • In CISA’s KEV catalogue since 8 May 2026: it is known to be exploited.
  • CVSS score 9.3: 9.0 or more.
  • CVSS score 9.3 (7.0 or more) and EPSS 0.89 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

LiteLLM versions 1.81.16 up to but not including 1.83.7 are vulnerable to SQL injection in the proxy's API key verification. An unauthenticated attacker can send a crafted Authorization header to any LLM API route, such as POST /chat/completions, and may read data from the proxy's database and possibly modify it. Upgrade to LiteLLM 1.83.7 or later; if that is not immediately possible, set disable_error_logs to true under general_settings.
