CVE-2026-8873 Medium · 6.4 CWE-79 May 27, 2026

Content Slideshow <= 2.4.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

The Content Slideshow plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 2.4.1 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.
