PHPGurukul Curfew e-Pass CVE-2025-12312

No vendor-released patch has been identified at the time of analysis. Immediate mitigation requires applying output encoding to the Fullname and Category parameters in view-pass-detail.php: use htmlspecialchars() or similar functions to convert special characters (e.g., <, >, &, ", ') to HTML entities before rendering in HTML context. For example, replace echo $Fullname with echo htmlspecialchars($Fullname, ENT_QUOTES, 'UTF-8'). Additionally, implement Content Security Policy (CSP) headers (e.g., Content-Security-Policy: default-src 'self'; script-src 'self') to restrict inline script execution and mitigate XSS impact even if encoding is bypassed. If available, upgrade PHPGurukul Curfew e-Pass Management System to a newer version after confirming it patches this vulnerability. If no patch exists, restrict access to view-pass-detail.php via network-level controls (e.g., IP whitelisting, VPN-only access) to reduce the number of high-privilege users who can be socially engineered into clicking malicious links. Monitor for unusual activity such as high-privilege accounts accessing the system via unexpected geographic locations or at unusual times, which may indicate compromised credentials.
