Impact

Exploitation status
No confirmed exploitation appears in the sources consulted. The record shows the CVE is not listed in CISA KEV, and no EPSS score is available.
Remediation and mitigation
- Identify every site where Widget Options is installed, including inactive copies, and record the installed version.
- Check the Patchstack entry and the official plugin source for a release newer than 4.2.3 and apply it as soon as it is verified.
- If no fixed release is available, consider deactivating or removing the plugin until a fix is published.
- Review which accounts hold the Contributor role and remove any that are unnecessary, since the record's description and privilege requirement point to this role.
Detection guidance
- Review web server and application logs for unexpected requests to plugin endpoints from low-privileged accounts.
- Check for new or modified PHP files, unexpected plugin changes, and unfamiliar administrative users.
- Monitor for outbound connections or processes that the site does not normally make.
Limitations of the available information
