CVE-2026-1074

Name of the Vulnerable Software and Affected Versions WP App Bar plugin for WordPress versions up to and including 1.5

Description The WP App Bar plugin for WordPress is susceptible to Stored Cross-Site Scripting through the app-bar-features parameter. This is a result of inadequate input sanitization and output escaping, coupled with a missing authorization check within the App Bar Settings class constructor. This allows unauthenticated attackers to inject arbitrary web scripts into multiple plugin settings, which will then execute when a user accesses the admin settings page.

Recommendations Update the WP App Bar plugin to a version newer than 1.5.
