What the vulnerability does
01Description
The BSK PDF Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 3.7.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file. This only affects multi-site installations and installations where unfiltered_html has been disabled.
