What is CVE-2026-13340?

The SVG Support WordPress plugin prior to version 2.5.17 fails to properly sanitize SVG files with the .svgz extension when uploaded by users who are permitted to do so. This oversight allows for the potential execution of malicious scripts embedded within these files, affecting users who view the uploaded content, including administrators. It is crucial for users of this plugin to upgrade to the latest version to mitigate this security risk.
