Technical description

A flaw was found in pulp-container when it authenticates to an upstream registry. Basic and bearer credentials from one remote are reused for later downloads in the same worker. A user who can sync a container remote, and can point that remote at a server they control, receives the username, password, or bearer token stored for a different remote, and can reuse that credential at the upstream registry. Content stored in Pulp is not changed, and the service is not stopped.

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
