How to Fix CVE-2026-7819

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: 9.15 
pip install pgadmin4>=9.15
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-2026-7819, 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 9.15), 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-61: UNIX Symbolic Link (Symlink) Following, where the product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. this could allow an attacker to cause the product to operate on unauthorized files. 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

Symbolic-link path traversal (CWE-61, CWE-22) in pgAdmin 4 File Manager. check_access_permission used os.path.abspath, which resolves '..' but does not resolve symbolic links, while the subsequent kernel write follows symlinks. An authenticated user could plant a symbolic link inside their own storage directory pointing outside it and induce pgAdmin to write to any path reachable by the pgAdmin process. Fix switches the access check to os.path.realpath for both source and destination, and adds an _open_upload_target helper that opens the target with O_NOFOLLOW (mode 0o600) to close the leaf-component TOCTOU between the access check and the open. File mode is hardened from 0o644 to 0o600. This issue affects pgAdmin 4: before 9.15.
