CVE-2021-47975: WordPress Plugin WP Learn Manager 1.1.2 Stored XSS

WP Learn Manager 1.1.2 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts through the fieldtitle parameter. Attackers can submit POST requests to the jslm_fieldordering page with XSS payloads in the fieldtitle field to execute arbitrary JavaScript when administrators view the field ordering interface.

Security readout for executives and security teams

Plain-English summary

WP Learn Manager 1.1.2 for WordPress has a stored cross-site scripting flaw. An unauthenticated attacker can save malicious script content that later runs in an administrator’s browser when the field ordering interface is viewed. This can create account and site-management risk, especially for public WordPress sites using this plugin.

Executive priority

Handle as a high-priority web application exposure for affected WordPress sites. The key business risk is attacker-controlled script execution in administrator browsers, which can lead to site compromise or unauthorized changes. Act quickly, but do not assume confirmed active exploitation from the provided evidence.

Technical view

CVE-2021-47975 is CWE-79 stored XSS in WP Learn Manager 1.1.2. The source bundle identifies the fieldtitle parameter on the jslm_fieldordering page as the injection point, with JavaScript executing when administrators view the field ordering interface. CVSS is 7.2, network exploitable, low complexity, no privileges required, scope changed.

Likely exposure

Exposure appears limited to WordPress installations running WP Learn Manager version 1.1.2. Internet-facing WordPress sites are the primary concern. The sources do not identify other affected versions, forks, or products.

Exploitation context

A public ExploitDB reference exists, but the bundle says KEV is false and provides no cited evidence of active exploitation. Treat this as publicly known and potentially reproducible, not confirmed exploited in the wild.

Researcher notes

The strongest evidence is the CVE description, VulnCheck advisory, and ExploitDB reference. Patch status is not established in the provided bundle. Avoid broad version assumptions beyond WP Learn Manager 1.1.2, and validate exposure by installation/version inventory before incident conclusions.

Mitigation direction

  • Inventory WordPress sites for WP Learn Manager and confirm installed versions.
  • Prioritize removal, disablement, or isolation of WP Learn Manager 1.1.2 where feasible.
  • Check vendor, WordPress plugin, and VulnCheck pages for fixed-version guidance.
  • Limit administrator access to trusted networks and accounts until remediated.
  • Review site backups and rollback options before changing production plugins.

Validation and detection

  • Confirm whether WP Learn Manager 1.1.2 is installed on each WordPress site.
  • Review plugin update history for any available vendor or WordPress.org remediation guidance.
  • Inspect web logs for unusual requests involving the field ordering interface.
  • Review administrative sessions and recent site changes for unexpected activity.
  • Check stored field-ordering values for unexpected script-like content.
