      <title>CVE-2026-111456 — Candlepin: consumer certificate can register systems in another organization</title>
      <link>https://db.gcve.eu/vuln/cve-2026-111456</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat Satellite 6.16 for RHEL 8, Red Hat Satellite 6.16 for RHEL 9, Red Hat Satellite 6.17 for RHEL 9, Red Hat Satellite 6.18 for RHEL 9&lt;/p&gt;
&lt;p&gt;A missing authorization check has been found in ConsumerResource.setupOwner() function of consumer registration module in the Candlepin package. The registration method checks permission to create a consumer only when the caller is a user. A consumer that authenticates with its identity certificate does not go through that check. A low-privileged network attacker or user who has a valid consumer certificate for one organization can register a new consumer in a different organization by supplying that organization&amp;#39;s key. The response includes an identity certificate for the new consumer. With that certificate, the attacker can view the target organization&amp;#39;s subscription pools. When the organization is not using simple content access, the attacker can attach that organization&amp;#39;s entitlements to the new consumer.&lt;/p&gt;</description>
