Stored XSS via unsanitized SVG uploads
Published Feb 15, 2022 · Updated Aug 3, 2024
Stored XSS in FlatPress 1.2.1 allows remote authenticated users to execute script in another user’s browser via a crafted SVG upload. The uploader accepts and serves SVG markup containing executable script without neutralizing that active content. Exploitation requires upload access and a user to open the stored SVG, exposing the browser session to actions available to that user.
