CVE-2025-66311 Details
Description
This admin plugin for Grav is an HTML user interface that provides a convenient way to configure Grav and easily create and modify pages. Prior to 1.11.0-beta.1, a Stored Cross-Site Scripting (XSS) vulnerability was identified in the /admin/pages/[page] endpoint of the Grav application. This vulnerability allows attackers to inject malicious scripts into the data[header][metadata], data[header][taxonomy][category], and data[header][taxonomy][tag] parameters. These scripts are stored in the page frontmatter and executed automatically whenever the affected page is accessed or rendered in the administrative interface. This vulnerability is fixed in 1.11.0-beta.1.
A stored cross-site scripting vulnerability has been identified in the Grav Admin Plugin, prior to version 1.11.0-beta.1. The issue resides in the '/admin/pages/[page]' endpoint, where the application fails to properly sanitize user input in several parameters. This allows attackers to inject malicious scripts into the page's metadata and taxonomy fields, which are then executed when the page is accessed in the admin interface.
Users can update to Grav Admin Plugin version 1.11.0-beta.1 or later to address this vulnerability.
