CVE-2026-15798

Name of the Vulnerable Software and Affected Versions Smart Slider 3 versions prior to 3.5.1.39

Description Insufficient input sanitization and output escaping allow authenticated attackers with contributor-level access and above to perform Stored Cross-Site Scripting. This is achieved by injecting arbitrary web scripts via the slider block attribute. The scripts execute when a user, specifically Editors or Administrators, opens the affected post within the WordPress block editor.

Recommendations Update Smart Slider 3 to version 3.5.1.39 or later.
