FKIE_CVE-2026-3996

Vulnerability from fkie_nvd - Published: 2026-03-21 04:17 - Updated: 2026-04-24 16:27
Summary
The WP Games Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [game] shortcode in all versions up to and including 0.1beta. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'width', 'height', 'src', 'title', 'description', 'game_url', 'main', and 'thumb', which are all directly concatenated into HTML output without any 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.
