Advisory
Source description from Wordfence Intelligence.
The Simple Link Directory plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 5.6.0 via deserialization of untrusted input from the 'settings' parameters as part of the Option Tree framework. This allows authenticated attackers 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.
