Security readout for executives and security teams
Plain-English summary
A WordPress plugin used for custom archive templates has an administrator-level stored XSS flaw through version 1.7.4. An attacker would need high privileges and user interaction, but successful abuse could run script in a browser and affect site trust, data, or sessions.
Executive priority
Handle during normal vulnerability remediation, faster for public or business-critical WordPress sites. This is not currently sourced as actively exploited, but stored XSS in admin-managed content can damage user trust and site integrity.
Technical view
CVE-2023-25490 is CWE-79 stored cross-site scripting in Eric Teubert Archivist – Custom Archive Templates <=1.7.4. The CVSS 3.1 score is 5.9 with network reachability, low complexity, high privileges required, user interaction required, and changed scope.
Likely exposure
Likely exposure is WordPress sites with the Archivist – Custom Archive Templates plugin installed at version 1.7.4 or earlier. The source bundle does not identify other affected products or platforms.
Exploitation context
The sources do not report active exploitation, and the CVE is not listed as KEV. The vulnerability requires administrator-level access and user interaction, reducing broad opportunistic risk but still mattering where admin accounts or workflows are weak.
Researcher notes
Evidence is limited. The title and description identify <=1.7.4, but the affected entry provides no CPEs and no fixed version. Do not assume exploit availability or remediation details beyond cited vendor guidance checks.
Mitigation direction
- Inventory WordPress sites for archivist-custom-archive-templates plugin usage.
- Prioritize sites running version 1.7.4 or earlier.
- Check vendor, WordPress, or Patchstack guidance for fixed versions or mitigations.
- Restrict administrator access to trusted users only.
- Review recent admin account activity for suspicious changes.
Validation and detection
- Confirm plugin name and installed version on each WordPress site.
- Check whether any exposed site runs version 1.7.4 or earlier.
- Verify whether a vendor-approved update or mitigation has been applied.
- Review security logs for unusual administrator template or content changes.
