This link is maintained to preserve external references.\n\n### Original Description\nPraisonAI before 4.6.78 exposes the MCP HTTP-stream transport without authentication by default: the CLI --api-key option defaults to None, and the server only enforces Authorization/Bearer checks when an API key is configured. When an operator runs 'praisonai mcp serve --transport http-stream' without an API key, an unauthenticated client (no Authorization header, and no Origin header, which is also permitted) can initialize a session, enumerate the available tools (tools/list), and invoke tools (tools/call). Additionally, the dispatcher forwards tool-call arguments to handlers without validating them against the advertised inputSchema. The server binds to 127.0.0.1 by default, so remote exploitation requires the operator to bind to a network-accessible address (e.g., --host 0.0.0.0).","public_affected_ranges":["<= 4.6.77"]}],"null_published_at":"2026-11-01T01:03:56.586Z","source_updated_at":"2026-10-08T21:58:36.000Z","source_disclosed_at":"2026-07-15T12:32:03.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T00:58:23.763Z"}],"next_cursor":null,"snapshot_revision":"42594"}
