How to fix CVE-2025-50857?

Within 24 hours: Identify all ZenTaoPMS instances in your environment and document their versions; implement immediate network access controls to restrict external access to the /module/ai/control.php endpoint. Within 7 days: Apply available security patches if your version is outside the vulnerable range (pre-18.11 or post-21.6.beta); if no patch is available for your version, evaluate upgrading to the latest stable release or implement WAF rules to block file uploads to the AI module. Within 30 days: Complete migration to a patched version, conduct forensic analysis of access logs for indicators of exploitation, and reset all credentials for accounts that may have been compromised.
