What the vulnerability does
The PDF Catalog for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pdfcatalog' AJAX action in all versions up to, and including, 1.1.18 due to insufficient input sanitization and output escaping.

An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers when they view affected pages. The vulnerability requires user interaction and can affect the site's integrity and confidentiality.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing data or performing actions on their behalf.
Potential impact on your site

Conditions required to exploit
Attacker needs a low-privilege account (e.g., subscriber or contributor) and the victim must view a page containing the injected script.
