Description
The Ditty plugin for WordPress is vulnerable to PHP Object Injection in all versions up to 3.1.38 via deserialization of untrusted input when adding a new ditty. 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 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.
