What it is

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.
