low-risk
Published 2021-10-15

The Job Manager WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/admin-jobs.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 0.7.25. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.
