Description
The Weaver Xtreme Theme Support plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 6.3.0 via deserialization of untrusted input from imported files. This allows authenticated attackers, with administrator-level privileges and above, to inject a PHP Object. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
