CVE-2021-39335 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. The WpGenius Job Listing WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/src/admin/class/class-wpgenious-job-listing-options.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 1.0.2.

EPSS estimates a 0.88% chance of exploitation in the next 30 days.
