Name of the Vulnerable Software and Affected Versions The Grid Gallery – Photo Image Grid Gallery WordPress plugin versions prior to 1.2.5

Description The issue arises from the improper sanitization of the title field for image galleries when added via the admin dashboard, resulting in an authenticated Stored Cross-Site Scripting issue. This allows attackers to inject malicious scripts into the website.

Recommendations For versions prior to 1.2.5, update to version 1.2.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin dashboard to minimize the risk of exploitation. Avoid using the title field for image galleries in the admin dashboard until the issue is resolved.
