WordPress vulnerability analysis and mitigation

Overview

The Image Photo Gallery Final Tiles Grid WordPress plugin before version 3.6.0 contains a stored Cross-Site Scripting (XSS) vulnerability.

This vulnerability was discovered and reported by Dmitrii Ignatyev, and was assigned CVE-2024-3710 (WPScan).

Technical details

The vulnerability allows users with a role as low as contributor to perform Stored Cross-Site Scripting attacks. The issue specifically involves the 'Additional CSS class on A tag' field in the gallery creation functionality, where malicious JavaScript can be injected.

Impact

If successfully exploited, this vulnerability could allow attackers with contributor-level access to execute stored XSS attacks against high-privilege users such as administrators. This could potentially lead to unauthorized actions being performed with administrator privileges when the malicious content is viewed (WPScan).

Mitigation and workarounds
