| Title | universal-tool-calling-protocol python-utcp 1.1.0 Improper Input Validation |
|---|
| Description | During a security audit of python-utcp, a high-risk validation flaw was identified in GraphQL and WebSocket protocol handlers. The implementation intends to allow only HTTPS/WSS or localhost exceptions, but the localhost exception is
implemented with startswith(...) checks.
Because of this, non-local domains that begin with 127.0.0.1. can bypass security checks and receive authenticated traffic. |
