Security readout for executives and security teams
Plain-English summary
CVE-2026-24587 affects the WordPress plugin AJAX Hits Counter + Popular Posts Widget through version 0.10.210305. It is a broken access control issue that can let a logged-in user perform actions they should not be authorized to perform. The expected business impact is limited integrity and availability impact, not data theft based on the provided CVSS details.
Executive priority
Treat this as a routine but timely WordPress plugin remediation item. Prioritize internet-facing WordPress sites with user registration or many authenticated users. It is not currently supported by sources as an emergency exploited-in-the-wild issue.
Technical view
The vulnerability is a missing authorization flaw, CWE-862, in the ajax-hits-counter plugin by kutsy. CVSS 3.1 is 5.4 with network access, low complexity, low privileges required, and no user interaction. The CVSS vector indicates no confidentiality impact, low integrity impact, and low availability impact. Affected versions are listed as through 0.10.210305.
Likely exposure
Exposure is limited to WordPress sites with the AJAX Hits Counter + Popular Posts Widget plugin installed at version 0.10.210305 or earlier. Exploitation requires an authenticated low-privilege user, so public sites with open registration, many contributors, or weak account governance have higher practical risk.
Exploitation context
The provided sources do not report active exploitation, public exploit code, or CISA KEV listing. The issue is still relevant because low-privilege authenticated users may be common on WordPress sites, especially membership, customer portal, community, or multi-author environments.
Researcher notes
Evidence is limited to the CVE record and Patchstack database reference. The bundle identifies missing authorization in ajax-hits-counter but does not provide endpoint details, proof-of-concept, exploit observations, or a fixed version. Avoid assuming unauthenticated exploitation; the CVSS vector requires low privileges.
Mitigation direction
- Inventory WordPress sites for the ajax-hits-counter plugin.
- Identify installations running version 0.10.210305 or earlier.
- Check vendor, WordPress plugin, or Patchstack guidance for an available fixed version.
- Update the plugin if a vendor-supported fixed release is available.
- Disable or remove the plugin if it is unnecessary or unsupported.
- Review and reduce low-privilege WordPress accounts where practical.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the installed plugin version and compare it to 0.10.210305.
- Check whether user registration or contributor accounts are enabled.
- Review site roles for unnecessary low-privilege users.
- Monitor vendor and vulnerability database entries for remediation updates.
