CVE-2025-2945: Remote Code Execution in PostgreSQL pgAdmin

CRITICAL SECURITY ALERT - CVE-2025-2945 requires immediate attention from all PostgreSQL pgAdmin users and administrators.

Executive Summary

In this analogy, your smart home is the vulnerable application, the voice commands are the input data, and the malicious command sequence represents the code injection that leads to unauthorized system control.

The Exploit Chain: From Vulnerability to System Compromise

This vulnerability can be exploited through the following process:

1. Reconnaissance: Attackers identify vulnerable PostgreSQL pgAdmin installations
2. Payload Crafting: Malicious input is created to trigger the vulnerability
3. Exploitation: The crafted payload is delivered to the vulnerable system
4. System Compromise: Successful exploitation leads to unauthorized access or code execution
