Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
SSRF: Recurring SSRF fixes across diverse URL-fetching paths indicate a systemic lack of a single, centralized egress guard. Each fix adds a different check (private IP ranges, protocol allowlist, URL allowlist, host allowlist) that may not be enforced on all sibling paths.
Auth Bypass: Dominant vulnerability class with 25+ fixes. Recurring issues include SSO/OAuth2 registration bypass, disabled-feature access, session handling, and role/team assignment errors. The breadth suggests fundamental flaws in the authentication/authorization model that are patched reactively.
Path Traversal: Path traversal fixes are scattered across many file-handling endpoints with varying validation approaches (rejecting '..', using File.getName(), canonicalization). This inconsistency creates high risk of a missed endpoint or a bypass via alternate encoding.
