CVE-2021-39344
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory (reason: Security Issue), and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
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.
