Description

Multiple plugins and/or themes for WordPress are vulnerable to Stored Cross-Site Scripting via the plugin's bundled lightGallery library (<= 2.8.3) in various versions due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Attack-Flow Graph

Executive Summary

This vulnerability involves multiple WordPress plugins and themes that use the lightGallery library (version 2.8.3 or earlier). Due to insufficient input sanitization and output escaping on user-supplied attributes, authenticated users with Contributor-level access or higher can inject malicious scripts into pages. These scripts execute whenever any user accesses the injected page, leading to Stored Cross-Site Scripting (XSS).

Impact Analysis

The vulnerability allows attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. This can lead to unauthorized actions such as stealing user credentials, session hijacking, defacement, or spreading malware to users who visit the affected pages. It compromises the integrity and security of the website and its users.
