The Red Hat Satellite /unattended/provision API endpoint is vulnerable to an authentication bypass due to a semantic logic flaw in host_verifier.rb. The application verifies the database state of a provisioning token rather than its actual presence in the incoming HTTP request. Because a host actively undergoing provisioning has an unexpired token in the database, the server's valid_host_token? method evaluates to true, granting access to the kickstart template even if the requester provides no token at all in the URL."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Satellite 6.16 for RHEL 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"foreman","defaultStatus":"affected","versions":[{"version":"0:3.12.0.23-1.el8sat","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:satellite:6.16::el8","cpe:/a:redhat:satellite:6.16::el9","cpe:/a:redhat:satellite_capsule:6.16::el8","cpe:/a:redhat:satellite_capsule:6.16::el9","cpe:/a:redhat:satellite_utils:6.16::el8","cpe:/a:redhat:satellite_utils:6.16::el9"]},{"vendor":"Red Hat","product":"Red Hat Satellite 6.16 for RHEL 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"foreman","defaultStatus":"affected","versions":[{"version":"0:3.12.0.23-1.el9sat","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:satellite:6.16::el8","cpe:/a:redhat:satellite:6.16::el9","cpe:/a:redhat:satellite_capsule:6.16::el8","cpe:/a:redhat:satellite_capsule:6.16::el9","cpe:/a:redhat:satellite_utils:6.16::el8","cpe:/a:redhat:satellite_utils:6.16::el9"]},{"vendor":"Red Hat","product":"Red Hat Satellite 6.17 for RHEL 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"foreman","defaultStatus":"affected","versions":[{"version":"0:3.14.0.22-1.el9sat","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:satellite:6.17::el9","cpe:/a:redhat:satellite_capsule:6.17::el9","cpe:/a:redhat:satellite_utils:6.17::el9"]},{"vendor":"Red Hat","product":"Red Hat Satellite 6.18 for RHEL 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"foreman","defaultStatus":"affected","versions":[{"version":"0:3.16.0.25-1.el9sat","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:satellite:6.18::el9","cpe:/a:redhat:satellite_capsule:6.18::el9","cpe:/a:redhat:satellite_utils:6.18::el9"]},{"vendor":"Red Hat","product":"Red Hat Satellite 6.19 for RHEL 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"foreman","defaultStatus":"affected","versions":[{"version":"0:3.18.0.14-1.el9sat","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:satellite:6.19::el9","cpe:/a:redhat:satellite_capsule:6.19::el9","cpe:/a:redhat:satellite_utils:6.19::el9"]},{"vendor":"Red Hat","product":"Red Hat Satellite 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"satellite:el8/foreman","defaultStatus":"affected","cpes":["cpe:/a:redhat:satellite:6"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:74503","name":"RHSA-2026:74503","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74504","name":"RHSA-2026:74504","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74505","name":"RHSA-2026:74505","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74506","name":"RHSA-2026:74506","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-12423","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2488956","name":"RHBZ#2488956","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-10-01T12:20:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-306","description":"Missing Authentication for Critical Function","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-306: Missing Authentication for Critical Function","workarounds":[{"lang":"en","value":"Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example.
