This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 87% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

A flaw was found in Katello's of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content.
