How the Exploit Works
CVE-2023-52200 is a combined Cross-Site Request Forgery (CSRF) and PHP Object Injection vulnerability. An attacker can exploit this by crafting a malicious request that, when executed by an authenticated administrator, can lead to the deserialization of untrusted data. This deserialization can result in arbitrary code execution on the server. Patchstack
