CVE-2020-10676Network attack vector

Cross-project access via unchecked namespace transfer

Published Dec 12, 2023 · Updated Aug 4, 2024

Incorrect authorization in SUSE Rancher 2.6.0 through 2.6.12 and 2.7.0 through 2.7.3 allows remote authenticated users to access other projects. The namespace-move path checks source-namespace update privileges without verifying access to the destination project, then preserves the mover's former permissions after transfer. Project Owner, Project Member, or equivalent custom-role access to the source project is required; successful abuse exposes project secrets and can consume the destination project's quota.
