Descriptions

NVD
Wordfence

The Simple Lightbox WordPress plugin before 2.9.4 does not validate and escape some of its attributes before outputting them back in a page/post, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

The Simple Lightbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.9.3 due to insufficient input sanitization and output escaping. 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.
