CVE-2026-111896 Details
Description
phpMyFAQ from 4.2.0-alpha before 4.2.0-beta contains a stored cross-site scripting vulnerability in SvgSanitizer that allows FAQ editors to store executable SVG files. Attackers can split script tags around removed tokens like processing instructions so single-pass removal reassembles them, executing script in the application origin when victims open the file.
A stored cross-site scripting vulnerability has been identified in phpMyFAQ versions 4.2.0-alpha prior to 4.2.0-beta. The issue resides in the SvgSanitizer component, allowing FAQ editors to upload and store executable SVG files. Exploitation involves manipulating script tags around removed tokens, such as processing instructions, to evade single-pass sanitization. This reassembly of the script tags results in the execution of scripts within the application origin when the files are accessed by victims.
Users are advised to update to phpMyFAQ version 4.2.0-beta, where this vulnerability has been patched.
