Soledad < 8.4.2 - Unauthenticated PHP Object Injection

Description

The Soledad theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 8.4.1 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable theme. 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.
