CVE-2025-11803

Name of the Vulnerable Software and Affected Versions WPSite Shortcode plugin for WordPress versions up to and including 1.2

Description The WPSite Shortcode plugin for WordPress is susceptible to Stored Cross-Site Scripting. This is due to insufficient input sanitization and output escaping in error messages. Specifically, the issue affects the 'format' shortcode attribute within the wpsite y shortcode and the 'before' attribute within the wpsite postauthor shortcode. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page.

Recommendations Update the WPSite Shortcode plugin to a version beyond 1.2.
