CVE-2025-11878

Name of the Vulnerable Software and Affected Versions ST Categories Widget plugin for WordPress versions prior to 1.0.1

Description The ST Categories Widget plugin for WordPress is susceptible to Stored Cross-Site Scripting through the plugin’s st-categories shortcode. This is caused by inadequate input sanitization and output escaping of user-provided attributes. Authenticated attackers with contributor-level access or higher can inject malicious web scripts into pages, which will then execute when a user views the affected page.

Recommendations Update the ST Categories Widget plugin to version 1.0.1 or later.
