A critical vulnerability in pgAdmin 4 version 9.11 allows authenticated users to bypass restore restrictions and execute arbitrary commands on the underlying host system.

This flaw involves a restore restriction bypass via key disclosure occurring in server mode. An authenticated user can intercept the restore process, extract the required security key, and inject meta-commands to gain command execution on the host.

The ability for an authenticated user to achieve arbitrary command execution on the host server represents a high risk to organizational data integrity and system availability. With a CVSS score of 7.4, this vulnerability enables lateral movement and potential full system compromise, particularly in multi-tenant or shared administrative environments. Unauthorized access to the pgAdmin host could lead to the exposure of sensitive database credentials and stored information.

Immediate Action: Update pgAdmin 4 to version 9.12 or higher to address the restriction bypass vulnerability.

Proactive Monitoring: Monitor pgAdmin server logs for unusual restore operations or unexpected shell activity originating from the pgAdmin process.

Compensating Controls: Restrict access to the pgAdmin web interface to trusted administrative users only and implement network-level access controls to limit exposure to the management console.

Public Exploit Available: No

Given the potential for complete host compromise, administrators should prioritize upgrading to version 9.12 immediately. Organizations should verify that their internal update processes are triggered for all instances of pgAdmin 4 currently running version 9.11 to neutralize this risk.
