GHSA-ppx3-28rw-8fpf: utcp-gql SSRF: CVE-2026-44661 fix not applied to the GraphQL and WebSocket plugins
The fix for CVE-2026-44661 (commit 5b16e43) added the ensure_secure_url() / is_secure_url() helpers and wired them into the three HTTP-family plugins, but it did not reach the GraphQL or WebSocket plugins. The GraphQL plugin (utcp-gql) still uses the startswith prefix check that the fix explicitly replaced, so http://127.0.0.1.attacker.example and http://localhost.evil.com pass it. The WebSocket plugin (utcp-websocket) performs no URL validation at all, even though its own docstrings state it enforces “WSS or localhost only.” Both plugins reach the same SSRF that CVE-2026-44661 was filed for, and because both attach the call template’s configured auth headers to the outbound connection, the SSRF can also leak API keys and OAuth tokens to an attacker-controlled host.
