JS Archive List <= 6.1.7 - Authenticated (Contributor+) PHP Object Injection

The JS Archive List plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 6.1.7 via deserialization of untrusted input [from the vulnerable parameter?|in the vulnerable function?]. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. 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.
