{"id":"CVE-2026-114612","aliases":["GHSA-7hp6-4w63-5g45"],"url":"https://o3.security/vulnerability/CVE-2026-114612","summary":"LiteLLM: Privilege Escalation to Proxy Admin via Cross-Domain Reuse of the Salt Key","details":"### Summary\n\nAn authenticated user with `internal_user` privileges can escalate to `proxy_admin` and achieve remote code execution. The proxy uses one encryption key for two purposes: sealing secrets at rest and minting session tokens. An attacker exploits this by requesting a new API key with a crafted metadata field containing a forged admin credential as the \"secret\" value. The proxy encrypts and returns this payload. When this value is then presented as a bearer token, the proxy decrypts it, trusts the forged admin identity, and grants full administrative access, including the ability to execute arbitrary commands via the MCP stdio endpoint.\n\n### Affected versions\n\nVersions later than 1.91.0 are exploitable in the default configuration. Versions 1.87.0 through 1.90.x are exploitable only if `EXPERIMENTAL_UI_LOGIN=true` was explicitly set.\n\n### Mitigation\n\nUpgrade to a patched version as soon as possible.\n\nIf you cannot upgrade immediately, set `EXPERIMENTAL_UI_LOGIN=false`. This disables the vulnerable authentication path but also breaks CLI SSO and Claude Code gateway login.\n\n### Impact\n\nAn internal user can escalate to proxy admin and execute arbitrary commands on the host.\n\n**Discovery Credit:** Hoa X.
