CVE-2026-83544Network attack vector

Stored XSS via unescaped animation data attributes

Published Sep 5, 2026 · Updated Sep 6, 2026

Stored XSS in WPSoul Greenshift before 13.2.0 allows remote authenticated users to inject scripts through block animation data. The GSAP animation renderer writes customProps, customPropsM, and multianimations values into HTML attributes without context-appropriate escaping. Contributor-level access is required to store the payload, which executes in the site origin when another user views the affected content.
