pip show vantage6

Analyze the terminal output to locate any version of Vantage6 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.8.0), your application is affected.

Note: The pip show vantage6 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-281: Improper Preservation of Permissions, where the product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended. In Vantage6, 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

### Impact Assigning existing users to a different organization is currently possible. It may lead to unintended access: if a user from organization A is accidentally assigned to organization B, they will retain their permissions and therefore might be able to access stuff they should not be allowed to access. ### Patches Update to 3.8.0 ### Workarounds None ### References None ### For more information If you have any questions or comments about this advisory: * Email us at [vantage6@iknl.nl](mailto:vantage6@iknl.nl)
