Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
CSRF: A failure to strictly validate the structural format of request bodies allowed non-object payloads to bypass CSRF token checks. This occurred because unexpected content types fell back to form-encoded parsing, leaving the application unprotected against cross-site requests.
Auth Bypass: The Content Security Policy (CSP) implementation used an incorrect encoding algorithm (hexadecimal instead of base64) for nonce generation. This violated the W3C specification, potentially weakening browser-enforced script execution protections.
