Security readout for executives and security teams
Plain-English summary
CVE-2026-24594 is a stored cross-site scripting issue in the WordPress Livemesh Addons for WPBakery Page Builder plugin through version 3.9.4. A high-privileged user could store unsafe content that runs in another user’s browser when viewed. Business urgency is moderate, with risk concentrated on WordPress sites using this plugin.
Executive priority
Treat as a moderate-priority WordPress plugin issue. It is not reported as actively exploited, but affected public sites should be reviewed promptly because stored XSS can affect user trust, site integrity, and administrative sessions.
Technical view
The issue is CWE-79 improper input neutralization during page generation in package addons-for-visual-composer. CVSS 3.1 is 5.9 with network attack vector, low complexity, high privileges required, user interaction required, and changed scope. The CVE record identifies affected versions as through <= 3.9.4.
Likely exposure
Exposure appears limited to WordPress installations with Livemesh Addons for WPBakery Page Builder installed at version 3.9.4 or earlier. Sites without the plugin, or with unaffected versions, are not indicated as affected by the provided sources.
Exploitation context
The provided sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation requires high privileges and user interaction, which reduces broad internet-scale risk but still matters on sites with many administrators, editors, or delegated content roles.
Researcher notes
Evidence is limited to the CVE metadata and Patchstack reference. The source bundle does not provide payload details, vulnerable parameters, or a named fixed version. Avoid assuming exploit availability or remediation beyond checking official vendor and Patchstack guidance.
Mitigation direction
- Inventory WordPress sites for the addons-for-visual-composer plugin.
- Identify installations running Livemesh Addons for WPBakery Page Builder <= 3.9.4.
- Check vendor or Patchstack guidance for a fixed version or official mitigation.
- Restrict high-privileged WordPress access to trusted users only.
- Prioritize remediation on public or business-critical WordPress sites.
Validation and detection
- Confirm the plugin is installed and record its exact version.
- Compare installed versions against the affected range: <= 3.9.4.
- Review whether untrusted users hold high-privileged WordPress roles.
- Check security monitoring for unusual admin or editor content changes.
- Track CVE and Patchstack updates for remediation status.
