What is CVE-2025-34177?

In pfSense CE's Suricata package, an issue has been identified where the policy_name parameter is not properly sanitized before being rendered on the webpage. This oversight can lead to stored cross-site scripting (XSS), allowing attackers with authenticated access privileges to inject malicious scripts that may affect other users. To mitigate this risk, updates have been implemented to ensure proper sanitization is enforced. Users are advised to apply the latest patches to safeguard against potential exploits.
