Description
The QA Assistants – Driven by data WordPress plugin up to version 5.3.0 is vulnerable to PHP Object Injection via the 'dlevent_ver' parameter. This vulnerability arises from unsafe deserialization without class restrictions and insufficient sanitization of input parameters, enabling unauthenticated attackers to inject malicious PHP objects. Exploitation involves triggering a scheduled event that automatically runs every two minutes without authentication, potentially leading to arbitrary file writes and remote code execution.
