Executive Summary

The Easy SVG Support plugin for WordPress has a vulnerability known as Stored Cross-Site Scripting (XSS) that affects all versions up to and including 4.0. This vulnerability arises because the plugin does not properly sanitize input or escape output when handling SVG file uploads. As a result, an attacker with Author-level access or higher can upload a malicious SVG file containing arbitrary web scripts. These scripts will then execute whenever any user accesses the infected SVG file.

Impact Analysis

This vulnerability can allow an attacker with Author-level access to inject malicious scripts into SVG files that are stored on the website. When other users view these SVG files, the malicious scripts execute in their browsers. This can lead to unauthorized actions such as stealing user session data, defacing the website, or performing actions on behalf of the user without their consent.
