WordPress Plugin Under Construction, Coming Soon & Maintenance Mode is prone to multiple vulnerabilities, including cross-site scripting and server-side request forgery vulnerabilities. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, allowing the attacker to steal cookie-based authentication credentials, or to make the vulnerable server perform port scanning of hosts in internal or external networks; other attacks are also possible. WordPress Plugin Under Construction, Coming Soon & Maintenance Mode version 1.1.1 is vulnerable; prior versions may also be affected.
