Vulnerability Overview
The Site Offline Or Coming Soon Or Maintenance Mode plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.4.2.

The impact of this vulnerability is unknown.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Site Offline Or Coming Soon Or Maintenance Mode <= 1.4.2 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Site Offline Or Coming Soon Or Maintenance Mode the fix is 1.4.4: builds <= 1.4.2 are affected, anything from 1.4.4 onward is not.
Remediation
Update to version 1.4.4, or a newer patched version
