Description

WordPress Plugin Maintenance Mode Under Construction Page Landing Page is prone to a possible remote code execution vulnerability because it fails to sufficiently sanitize user-supplied input. Successful exploitation may allow attackers to execute arbitrary commands with the privileges of the user running the application, to compromise the application or the underlying database, to access or modify data or to compromise a vulnerable system. WordPress Plugin Maintenance Mode Under Construction Page Landing Page version 1.0.9 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 1.1.1 or latest
