Summary

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.

Risk Assessment

An attacker can obtain credentials for a different remote and reuse them to gain unauthorized access to the registry, potentially leading to data confidentiality breach.

Recommendation

Update pulp-container to a patched version and ensure credential isolation between remotes.
