In versions up to and including 0.8.3, users with only `VIEW` access to an MCP server can retrieve the server&#8217;s decrypted admin-managed secrets through `GET \/api\/mcp\/servers` and `GET \/api\/mcp\/servers\/:serverName`. The returned config includes plaintext values for `apiKey.key` and `oauth.client_secret`. This allows viewers of a shared MCP server to exfiltrate the underlying provider credentials. Version 0.8..4 contains a patch. Other remediations include: never returning decrypted admin-managed secrets to non-owners; redacting apiKey.key and oauth.client_secret from all API responses consider returning only boolean presence indicators for secrets, similar to the auth-values route pattern; and, if owners need to edit configs without re-entering secrets, preserving secrets server-side and returning placeholders instead of plaintext.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>LibreChat is an enhanced ChatGPT clone that supports multiple AI providers.
