Description
YesWiki before 4.7.0 contains a stored cross-site scripting vulnerability that allows low-privilege authenticated users to upload unsanitized SVG files through the bazar ImageField class. Attackers can submit a malicious SVG via the image field of the entries API, which is served as image/svg+xml and executes script for users viewing the entry or file.
