Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize identifying which WordPress sites use the Vedrixa Forms plugin and verify if they are running version 1.1.1 or older. Because this vulnerability allows authenticated users to modify form structures, focus on containing the impact by disabling the plugin on affected sites or isolating them from the network if patching cannot be immediately applied.
- Update plugin to version 1.1.2.
- Disable plugin if patching is delayed.
- Monitor for unauthorized form changes.
