Attackers can silently manipulate AI responses via callbacks or MCP. Upgrade immediately to v1.83.14-stable.

  • •Three chained CVEs (47101, 47102, 40217) enable default user → full server compromise via authorization bypass, privilege escalation, and code execution
  • •Compromised proxy exposes all provider API keys, credentials, database secrets, and enables silent response manipulation in transit to AI agents
  • •Affects any org running LiteLLM to broker AI model access; upgrade immediately to v1.83.14-stable or later
