6.4MEDIUM

What is CVE-2026-5361?

The Envira Gallery Lite plugin for WordPress has a vulnerability that enables authenticated attackers with Author-level access and higher to execute arbitrary web scripts through stored cross-site scripting. This flaw arises from inadequate input sanitization in the update_gallery_data() function and improper output escaping in the gallery_init() function. Specifically, the arrows parameter is not sanitized correctly, leading to the potential for JavaScript expression injection when the value is output in the inline JavaScript configuration, posing significant security risks to site users.
