Researcher notes
Evidence is sparse: the bundle provides CVE metadata, CVSS, CWE-352, affected plugin/version, and one Patchstack reference. It does not provide exploit details, proof of exploitation, or a confirmed patch version.
Mitigation direction
- Inventory WordPress sites for the easy-custom-css plugin and version.
- Check vendor and Patchstack guidance for a fixed release or workaround.
- Disable or remove the plugin where no safe guidance is available.
- Limit WordPress administrative access to trusted users and devices.
- Monitor site content changes for unexpected stored script behavior.
Validation and detection
- Confirm whether Easy Custom CSS is installed on each WordPress site.
- Record installed plugin versions and flag versions <=1.0.
- Review WordPress audit logs for unexpected plugin setting changes.
- Check public pages for unauthorized persistent script content.
- Track CVE and Patchstack entries for updated remediation details.
