What the vulnerability does
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 3.3.12 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.

An attacker with low-level user access can inject malicious scripts that execute in other users' browsers when they view affected pages. The vulnerability requires user interaction and can affect users across the site. Update to a version newer than 3.3.12.
What an attacker can do
Inject malicious scripts that run in other users' browsers to steal session tokens or perform actions on their behalf.
Potential impact on your site
