Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Red Hat is not aware of a practical temporary workaround that fully mitigates this issue or meets Red Hat Product Security's standards for usability, deployment, applicability, or stability.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher description

An expression language injection has been found in the HeaderContentGuard.permit function in publication.py of the content guard in the Pulpcore package. The guard is supposed to check a value in a request header. It saves a jq filter and runs that filter against the header when a client asks for content. The filter is not limited to the header, and jq's env builtin also returns the environment of the content process. A low-privileged network attacker or user who can create a header content guard and attach it to a distribution can save a filter that reads that environment. The content request is allowed or denied according to the filter result. Repeating the request lets that attacker or user recover the environment, including Pulp settings held there, such as the Django secret key or the database password.
