CVE-2026-1634

Name of the Vulnerable Software and Affected Versions Subitem AL Slider versions prior to 1.0.1

Description The Subitem AL Slider plugin for WordPress is susceptible to Reflected Cross-Site Scripting. This is due to insufficient input sanitization and output escaping related to the $ SERVER['PHP SELF'] parameter. An unauthenticated attacker could inject arbitrary web scripts into pages, which would execute if a user is tricked into performing an action, such as clicking a link.

Recommendations Update the Subitem AL Slider plugin to version 1.0.1 or later.
