What is CVE-2020-35938?

The Post Grid plugin for WordPress prior to version 2.0.73 contains vulnerabilities that allow remote authenticated attackers to execute arbitrary PHP code through insecure unserialization of data. The flaw arises when a specially crafted payload is sent via AJAX in the source parameter during a specific action, potentially compromising the security of the system. Proper validation and sanitization of user inputs are crucial to mitigate this risk.
