The String Locator plugin for WordPress is vulnerable to deserialization of untrusted input via the 'string-locator-path' parameter in versions up to, and including 2.5.0. This makes it possible for unauthenticated users to call files using a PHAR wrapper, granted they can trick a site administrator into performing an action such as clicking on a link, 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. It also requires that the attacker is successful in uploading a file with the serialized payload.

The InstaWP Connect plugin for WordPress is vulnerable to unauthorized access of data, modification of data and loss of data due to a missing capability check on the 'events_receiver' function in versions up to, and including, 0.0.9.18.

The String locator plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.6.6 via deserialization of untrusted input in the 'recursive_unserialize_replace' function.

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. An administrator must perform a search and replace action to trigger the exploit.
