How to Fix CVE-2026-24178

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

nvflare fixed: 2.7.2 
pip install nvflare>=2.7.2
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 nvflare

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-24178, inspect your installed packages using pip:

pip show nvflare

Analyze the terminal output to locate any version of NVIDIA NVFlare Dashboard in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
