Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers can bypass authentication and hijack accounts by exploiting identity providers that return unverified emails, leading to unauthorized account merging. This risk is tracked under CVE-2026-41574.
Auth Bypass: WebAuthn sign-up flows initially trusted client-asserted user identifiers rather than performing proper challenge verification matching, allowing attackers to forge registration credentials.
Open Redirect: Validation rules for custom redirects were repeatedly bypassed due to loose regex patterns, failure to canonicalize paths, case-sensitivity issues, and weak wildcard glob-matching implementations.
