CVE-2023-5742Network attack vector

Authenticated stored XSS via shortcode attributes

Published Nov 22, 2023 · Updated Apr 8, 2026

Stored cross-site scripting in EasyRotator for WordPress 1.0.14 and earlier allows remote authenticated users to inject arbitrary scripts through easyrotator shortcode attributes. The shortcode handler insufficiently sanitizes user-supplied attributes and fails to escape them when rendering page content, storing the payload for later execution. Contributor-level or higher WordPress permissions are required, and the script runs when another user accesses the injected page, enabling bounded confidentiality and integrity impact in that browsing context.
