CVE-2025-47493Network attack vector

Contributor-level browser script execution via crafted block

Published May 7, 2025 · Updated Apr 28, 2026

DOM-based XSS in Ultimate Blocks 3.2.9 and earlier allows remote authenticated users to run script via a crafted Content Toggle Panel block. The vendor changelog identifies that block as the affected locus, but no public source discloses the untrusted DOM source or unsafe sink. Contributor-level access is required to supply the content, and exploitation requires another user to render it in a browser.
