Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Server-Side Request Forgery: Processing out-of-band WS-Addressing headers like wsa:ReplyTo or wsa:FaultTo can allow external peers to trigger Server-Side Request Forgery (SSRF) and DNS rebinding attacks if destination URIs are not strictly validated against a private IP and host allowlist.
Auth Bypass: Failing to bind message replay detection components (nonce, timestamp, and SAML one-time-use caches) into the incoming validation context allows attackers to replay intercepted WS-Security messages.
XXE: Evaluating XPath expressions over un-hardened XML Stream or SAX sources allows attackers to execute XML External Entity (XXE) injection attacks, leaking local files or internal resources.
