Description
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a collection that allows downloadable SVG uploads can store a malicious SVG that bypasses sanitization and executes attacker-controlled JavaScript when a user downloads and opens the SVG. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
