Technical details
The vulnerability is a stored cross-site scripting (XSS) vulnerability in SVG file upload handling that fails to sanitize JavaScript embedded in SVG files across all upload routes. An attacker with Author role or higher permissions can upload a crafted SVG file containing malicious JavaScript that will execute when any user opens or views the file. The attack requires the optional unfiltered file uploads feature to be explicitly enabled in plugin settings.
