How to Fix CVE-2022-0959

To remediate this vulnerability, upgrade all affected Pgadmin4 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pgadmin4 fixed: 6.7 
pip install pgadmin4>=6.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show pgadmin4

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-0959, inspect your installed packages using pip:

pip show pgadmin4

Analyze the terminal output to locate any version of Pgadmin4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.7), your application is affected.

Note: The pip show pgadmin4 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Pgadmin4, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

When run in server mode, pgAdmin 4 allows users to store files on the server under individual storage directories. Files such as SQL scripts may be uploaded through the user interface. The URI to which upload requests are made fails to validate the upload path to prevent path traversal techniques being used to store files outside of the storage directory. A malicious, but authorised and authenticated user can construct an HTTP request using their existing CSRF token and session cookie to manually upload files to any location that the operating system user account under which pgAdmin is running has permission to write.
