## What is CVE-2023-4314?

CVE-2023-4314 is a high-severity unsafe deserialization vulnerability in Unknown wpDataTables, published on 11 Sep 2023. An attacker needs administrator access to exploit it, with no action from the victim.

The wpDataTables WordPress plugin before 2.1.66 does not validate the "Serialized PHP array" input data before deserializing the data. This allows admins to deserialize arbitrary data which may lead to remote code execution if a suitable gadget chain is present on the server. This is impactful in environments where admin users should not be allowed to execute arbitrary code, such as multisite.
