Description

WordPress Plugin ThemeREX Addons is prone to a 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 ThemeREX Addons versions greater than 1.6.50 are vulnerable.
