Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers can bypass authentication completely by sending empty POST requests during the Source stage, causing the flow engine to skip validation checks and mark the stage as successful. This vulnerability is tracked under CVE-2026-49448.
SAML Signature Bypass: Improper validation of signature Reference URIs and target IDs allowed XML signature wrapping attacks. Attackers could inject malicious assertions into SAML responses to bypass signature verification mechanisms entirely (CVE-2026-25922).
Privilege Escalation: Under CVE-2024-37905, authenticated users could modify the owner (user) field of existing API tokens within serializers because the fields were not validated as read-only, leading directly to admin account takeover.
