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.","published_at":"2026-10-01T16:21:52.891000Z","last_modified_at":"2026-10-08T13:16:40.427000Z","cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-306"],"nvd_references":["https://access.redhat.com/errata/RHSA-2026:74503","https://access.redhat.com/errata/RHSA-2026:74504","https://access.redhat.com/errata/RHSA-2026:74505","https://access.redhat.com/errata/RHSA-2026:74506","https://access.redhat.com/security/cve/CVE-2026-12423","https://bugzilla.redhat.com/show_bug.cgi?id=2488956"],"vuln_status":"Analyzed","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-10-01T17:38:54.199659Z","updated_at":"2026-10-11T21:36:59.216424Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"redhat","vendor_name":"RedHat","product_slug":"satellite","product_name":"satellite","version_start":"6.16","version_start_inclusive":true,"version_end":"6.16.4","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:redhat:satellite:*:*:*:*:*:*:*:*"},{"vendor_slug":"redhat","vendor_name":"RedHat","product_slug":"satellite","product_name":"satellite","version_start":"6.0","version_start_inclusive":true,"version_end":"6.0","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:redhat:satellite:6.0:*:*:*:*:*:*:*"},{"vendor_slug":"theforeman","vendor_name":"theforeman","product_slug":"foreman","product_name":"foreman","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:a:theforeman:foreman:-:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:74503","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74504","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74505","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74506","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-12423","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2488956","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-10-01T16:21:52.891000Z","label":"CVE published","source":null}]}
