XSS in Progressplanner Aaa Autoload Optimizer

CVE-2026-119211

The AAA Autoload Optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'option_page' parameter in all versions up to, and including, 1.7.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the plugin's Option Tracking setting to be configured to 'Legacy' mode, and succeeds despite WordPress ultimately returning HTTP 403 to the low-privileged caller because the vulnerable 'all' filter fires before the capability check in wp-admin/options.php.
