Slider Revolution < 6.6.19 - Authenticated (Author+) PHP Object Injection

The Slider Revolution plugin for WordPress is vulnerable to PHP Object Injection in all versions up to 6.6.19 (exclusive) via deserialization of untrusted input when importing a new slider. This makes it possible for authenticated attackers, with author-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. 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.
