The content request that runs the filter needs no further account. The flaw is reachable in pulpcore's default configuration.\nThe vulnerable code was introduced in pulpcore 3.39.0 when the header content guard was added.\n```\nRed Hat Ansible Automation Platform 2.6 and 2.7 include this header check. A user who is allowed to create the check and attach it to a repository can read the environment of the content service. On these versions the application secret and the database password are stored in the settings file, so they are not part of that environment. The impact on Automation Platform 2.6 and 2.7 is Low with 4.3 CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N\n```\n```\nRed Hat Satellite does not use this guard. Katello installs only the RHSM certificate guard, and Pulp API authentication is the Satellite service certificate mapped to the internal pulp admin. A Satellite user cannot create or attach the header guard. Satellite is not affected.\n```\n```\nPulpcore in RHUI-5 does not create this guard. Content customers are authorized by the CDS entitlement check, and the RHUA nginx allows /pulp/api/v3/ only from localhost. A remote user cannot create the guard. RHUI 5 is not affected.\n```", "threat_severity": "Moderate"}
