Medium (4.8) in kajoom kjm admin notices. EPSS 1.1% chance of exploitation in the next 30 days.
The KJM Admin Notices WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/admin/class-kjm-admin-notices-admin.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 2.0.1. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.
