CVE-2025-60138Network attack vector

Stored XSS via unescaped Post Carousel content

Published Sep 26, 2025 · Updated Sep 26, 2025

Stored XSS in the Post Carousel block in SKT Blocks 2.6 and earlier allows remote authenticated users to inject arbitrary scripts. The block renderer stores contributor-supplied content without sufficient input sanitization or output escaping, then emits it into pages. Contributor-level access is required, and the script runs in a visitor's browser when the affected page is viewed, enabling actions in that visitor's session.
