PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 PR contains tests

🔒 Security concerns CSRF and weak origin validation: The endpoint performs state-changing actions via GET. While adding a Referer check helps, it is not a robust CSRF defense and can be error-prone. Additionally, using startsWith() on the Referer allows prefix-matching issues (e.g., https://allowed.com.attacker.com). Prefer: Parsing the Referer and comparing exact scheme/host/port against a strict allowlist. Considering a POST with CSRF protection, or verifying a signed token audience/host claim. Ensuring SameSite cookie settings align with this flow.

⚡ Recommended focus areas for review Weak Origin Check Using startsWith() on the Referer can be bypassed by lookalike domains (e.g., allowed.com.attacker.com). Parse the Referer URL and compare scheme/host/port exactly to serverUrlUtils.getUrl(), or use a strict allowlist. String referer = request.getHeader("Referer"); String allowedDomain = serverUrlUtils.getUrl(); boolean validOrigin = (referer != null && referer.startsWith(allowedDomain)); if (!validOrigin) { return new RedirectView("/settings?success=false&message=Invalid request origin"); } Referer Optional Many clients (email apps, privacy settings) omit the Referer; this would cause false negatives and block legitimate verification attempts. Consider a fallback (e.g., Origin/Host checks, token audience claim) or make the Referer requirement explicit in UX and tests (add a test for null Referer). String referer = request.getHeader("Referer"); String allowedDomain = serverUrlUtils.getUrl(); boolean validOrigin = (referer != null && referer.startsWith(allowedDomain)); if (!validOrigin) { return new RedirectView("/settings?success=false&message=Invalid request origin"); }
