Summary
The Woostify plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.5.0 This is due to insufficient input sanitization and output escaping in the bundled Lity.js lightbox library, where user-controlled input from the href attribute is concatenated directly into a jQuery HTML string without sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
