For versions provisionally classified as affected before 2.1.2, `trusted-repos-policy` compares an image's `registry` hostname against `reject lists` and `allow lists` case-sensitively even though `registry` DNS names are case-insensitive. An image with an uppercase or mixed-case `registry` hostname can miss a rejection rule for the equivalent lowercase host, so the admission policy accepts a resource whose container runtime pulls the same prohibited image. Only reject-list configurations have this bypass: allow-list configurations fail closed by over-denying differently cased hostnames. The security consequences depend on the configured rejection policy and deployment environment. This issue is fixed in version 2.1.2.\nhttps://www.cve.org/CVERecord?id=CVE-2026-63121https://github.com/kubewarden/policies/security/advisories/GHSA-8p62-9vh2-272phttps://github.com/kubewarden/policies/commit/bc5597fcbbb0bc464b714ca7ff645c9743dea41bhttps://github.com/kubewarden/policies/tree/trusted-repos-policy/v2.1.2#kubewarden #policies#CVE_2026_63121#bot", "url": "https://infosec.exchange/users/cve/statuses/117532163345983030"}, {"timestamp": "2026-10-30T22:16:58.123Z", "date_only": false, "value": "2026-10-30T22:16:58.123", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63121", "record": "FKIE_CVE-2026-63121", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-05T02:56:06.807Z", "date_only": false, "value": "2026-11-05T02:56:06.807176Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-63121", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-05T02:56:06.807Z", "date_only": false, "value": "2026-11-05T02:56:06.807176Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63121", "record": "FKIE_CVE-2026-63121", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-05T02:56:16.633Z", "date_only": false, "value": "2026-11-05T02:56:16.633Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-63121", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-05T02:56:16.633Z", "date_only": false, "value": "2026-11-05T02:56:16.633Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-63121", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-05T03:17:30.417Z", "date_only": false, "value": "2026-11-05T03:17:30.417", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-63121", "record": "FKIE_CVE-2026-63121", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-07T04:30:36.492Z", "anchors": {"origin": {"timestamp": "2026-10-30T22:08:03.004Z", "date_only": false, "value": "2026-10-30T22:08:03.004Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63121", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-30T22:08:03.004Z", "date_only": false, "value": "2026-10-30T22:08:03.004Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63121", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 627753.488758, "hours": 174.37596909944443, "days": 7.265665379143518, "min_seconds": 627753.488758, "max_seconds": 627753.488758, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-30T22:08:03.004Z", "date_only": false, "value": "2026-10-30T22:08:03.004Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-63121", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-07T04:30:36.492Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
