CVE-2024-4413 is a critical PHP Object Injection vulnerability in the MotoPress Hotel Booking Lite WordPress plugin (versions up to 4.11.1) caused by deserialization of untrusted data. This unsafe deserialization allows unauthenticated attackers to inject PHP objects. Although the vulnerable plugin does not contain a known POP chain to facilitate exploitation on its own, the presence of additional plugins or themes with POP chains on the target system could enable attackers to perform destructive or unauthorized actions such as arbitrary file deletion, sensitive data retrieval, or remote code execution.

Successful exploitation can lead to complete compromise of the affected WordPress site, including confidentiality, integrity, and availability impacts. Specifically, attackers could delete arbitrary files, retrieve sensitive information, or execute arbitrary code if a suitable POP chain exists in the environment. The vulnerability is exploitable remotely without authentication, increasing its risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to limit exposure by disabling or removing the vulnerable plugin if possible. Monitor vendor channels for updates and apply patches promptly once available. Avoid installing untrusted plugins or themes that could provide POP chains that facilitate exploitation.
