**Name of the Vulnerable Software and Affected Versions** vantage6 versions prior to 5.0.0 **Description** Malicious algorithms can potentially access input and output files belonging to other algorithms. **Recommendations** Update to version 5.0.0. As a temporary workaround, verify and restrict the algorithm containers that are allowed to run on the node.

**Name of the Vulnerable Software and Affected Versions** vantage6 versions prior to 4.5.0rc3 **Description** The issue allows collaboration administrators to add extra organizations to their collaboration, extending their influence. They can create new users for which they know the passwords and use this access to read task results of other collaborations that the included organization is involved in. This is limited to relatively trusted users with access to manage a collaboration, which reduces the impact. **Recommendations** For versions prior to 4.5.0rc3, update to version 4.5.0rc3 or later to resolve the issue. As a temporary workaround, consider restricting the ability of collaboration administrators to add new organizations or create new users until the update can be applied.

**Name of the Vulnerable Software and Affected Versions** vantage6 versions prior to 4.2.0 **Description** The vantage6 technology is used to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). There are no checks on whether the input is encrypted if a task is created in an encrypted collaboration. This allows a user to accidentally create a task with sensitive input data that will then be stored unencrypted in a database. **Recommendations** For versions prior to 4.2.0, ensure that the encryption setting is correctly set when creating tasks in encrypted collaborations to prevent sensitive input data from being stored unencrypted in the database. As a temporary workaround, consider double-checking the encryption settings for each task created in an encrypted collaboration until a patch is applied.
