WordPress Plugin String locator is prone to a deserialization vulnerability. Attackers can possibly exploit this issue to call files using a PHAR wrapper that will deserialize and call arbitrary PHP Objects that can be used to perform a variety of malicious actions, granted a POP chain is also present. WordPress Plugin String locator version 2.5.0 is vulnerable; prior versions may also be affected.
