A critical unauthenticated PHP Object Injection vulnerability in the CRM Perks Integration for Salesforce creates a severe risk of full system compromise.

This vulnerability is an unauthenticated PHP Object Injection flaw. Attackers can bypass authentication to inject malicious objects, which are deserialized by the application, potentially resulting in remote code execution.
