Description
The Gosign – Posts Slider Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'posts-slider-block' block in all versions up to, and including, 1.1.0 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.
