CVE-2021-39335: WpGenius Job Listing <= 1.0.2 Authenticated Stored Cross-Site Scripting

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. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.

Security readout for executives and security teams

Plain-English summary

This issue lets a logged-in administrator store malicious script inside the WpGenius Job Listing WordPress plugin configuration. The business risk is mainly tenant, administrator, or visitor trust impact on sites where administrators are normally blocked from unfiltered HTML.

Executive priority

Treat as a moderate cleanup item, not an emergency, unless the plugin is present on shared, multisite, or high-trust public WordPress properties.

Technical view

CVE-2021-39335 is authenticated stored XSS in WpGenius Job Listing versions up to 1.0.2. Insufficient validation and sanitization in admin option handling can store script through several parameters. CVSS 3.1 is 5.5, requiring high privileges, with changed scope and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites running WpGenius Job Listing up to and including 1.0.2, especially multisite or hardened sites where unfiltered_html is disabled for administrators.

Exploitation context

The sources describe administrator-level authenticated stored XSS. KEV is false, and the provided sources do not establish active exploitation in the wild.

Researcher notes

Evidence points to an authenticated administrative stored XSS in option handling. The provided bundle names affected versions but does not provide a confirmed fixed version or active exploitation evidence.

Mitigation direction

  • Inventory WordPress sites for WpGenius Job Listing versions up to 1.0.2.
  • Check vendor, WordPress plugin, and Wordfence guidance for a supported fixed release.
  • Restrict administrator access to trusted users until remediation is complete.
  • Disable or remove the plugin if no supported fix is available and business use is low.

Validation and detection

  • Confirm whether wpgenious-job-listing is installed and record the exact version.
  • Verify whether the site is multisite or has unfiltered_html disabled.
  • Review plugin job-listing option fields for unexpected stored script content.
  • Audit administrator accounts with access to the plugin settings.
