CVE-2026-6735

A flaw was found in PHP, specifically within the PHP-FPM status page. Due to improper sanitation of user data, a remote attacker can craft a malicious URL. When a user views the PHP-FPM status page with this crafted URL, it can lead to the execution of arbitrary JavaScript code (Cross-Site Scripting or XSS) on their machine, potentially compromising their browser session or leading to further attacks.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Restrict network access to the PHP-FPM status page to trusted internal networks or localhost. This can be achieved by configuring web server access controls (e.g., Apache httpd or Nginx) to deny external access to the status page URL. If the PHP-FPM status page functionality is not required, it should be disabled in the PHP-FPM configuration. Any changes to web server or PHP-FPM configuration may require a service reload or restart to take effect.
