Authenticated script execution in victim browsers
Published Oct 28, 2024 · Updated May 11, 2026
DOM-based XSS in CozyThemes Cozy Blocks 2.0.18 and earlier allows remote authenticated users to execute script in another user's browser. Patchstack has not published the affected block, input property, or client-side source-to-sink operation that mishandles untrusted data. Low-privilege access and user interaction are required; successful exploitation can read or modify data available to the victim's browser context.
