Security readout for executives and security teams

Plain-English summary

This is a stored cross-site scripting issue in the WordPress Add User Role plugin version 0.0.1 and earlier. An authenticated administrator-level user could store script content that later runs in another user’s browser. The business risk is constrained by high privileges required, but affected sites should still treat it as a real integrity and account-risk issue.

Executive priority

Handle during normal vulnerability remediation, faster for public or business-critical WordPress sites. The required administrator privileges reduce likelihood, but stored XSS can still support account compromise, content tampering, and trust damage if an admin account is misused.

Technical view

CVE-2022-37403 is CWE-79 in Nikhil Vaghela’s Add User Role WordPress plugin <= 0.0.1. The CVSS 3.1 score is 4.8 with PR:H and UI:R, indicating exploitation requires administrator-level authentication and user interaction. Impact is limited confidentiality and integrity loss with no availability impact stated.

Likely exposure

Exposure is limited to WordPress sites that installed Add User Role version 0.0.1 or earlier. The source bundle does not identify affected core WordPress, other plugins, or downstream products.

Exploitation context

The CVE is not listed as KEV, and the provided sources do not cite active exploitation. The issue is stored XSS, but no public exploit status or weaponized details are provided in the bundle.

Researcher notes

Evidence supports authenticated admin-plus stored XSS only. The CVSS vector shows network access, low complexity, high privileges, required user interaction, changed scope, low confidentiality and integrity impact, and no availability impact. No fixed version is named in the supplied sources.

Mitigation direction

  • Inventory WordPress sites for the Add User Role plugin.
  • Disable and remove the plugin where it is not required.
  • Check vendor and WordPress plugin guidance for fixed or retired status.
  • Restrict administrator access to trusted users only.
  • Review stored plugin-managed data before re-enabling production use.

Validation and detection

  • Confirm whether Add User Role is installed on each WordPress site.
  • Verify whether the installed version is 0.0.1 or earlier.
  • Identify administrator accounts with access to affected plugin functions.
  • Review administrative activity for unexpected content or settings changes.
  • Document compensating controls if no vendor fix is available.
