Vulnerability Overview

The AVIF & SVG Uploader plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in version 1.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file. CVE-2024-9238 appears to be a duplicate of this issue.

Technical Analysis

REMEDIATION: Update to version 1.1.1, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
