{"id":"GHSA-49pm-43hf-6xfq","summary":"IPAM controller service account granted unnecessary full access to Secrets","details":"### Impact\n\nIPAM is the IP address Manager for Cluster API Provider Metal3. The IPAM controller's ClusterRole granted full CRUD permissions (create, delete, get, list, patch, update, watch) on core/v1 Secrets. The controller never accesses Secrets during normal operation. If the controller pod were compromised (e.g. via supply chain attack or container escape), an attacker could leverage these excessive  permissions to read, modify, or delete Secrets in the namespace, potentially exposing credentials and other sensitive data.\n\nAll users running ip-address-manager versions prior to the patched releases are affected.\n\n### Patches\n\nFixed in:\n- v1.11.7\n- v1.12.4\n- v1.13.0\n\nUsers should upgrade to the patched version for their release branch.\n\n### Workarounds\n\nManually remove the Secrets resource entry from the metal3-ipam-controller-manager-role ClusterRole:\n\n```yaml\n# Remove this entire block from the ClusterRole\n- apiGroups:\n  - \"\"\n  resources:\n  - secrets\n  verbs:\n  - create\n  - delete\n  - get\n  - list\n  - patch\n  - update\n  - watch\n```\n\n### Resources\n\n- https://github.com/metal3-io/ip-address-manager/pull/1355\n- https://github.com/metal3-io/ip-address-manager/pull/1356 (backport to release-1.12)\n- https://github.com/metal3-io/ip-address-manager/pull/1357 (backport to release-1.11)","aliases":["CVE-2026-47190","GO-2026-5117"],"modified":"2026-06-25T18:56:25.129963496Z","published":"2026-05-29T18:24:45Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-05-29T18:24:45Z","nvd_published_at":"2026-06-12T16:16:29Z","cwe_ids":["CWE-250"]},"references":[{"type":"WEB","url":"https://github.com/metal3-io/ip-address-manager/security/advisories/GHSA-49pm-43hf-6xfq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47190"},{"type":"WEB","url":"https://github.com/metal3-io/ip-address-manager/pull/1355"},{"type":"WEB","url":"https://github.com/metal3-io/ip-address-manager/pull/1356"},{"type":"WEB","url":"https://github.com/metal3-io/ip-address-manager/pull/1357"},{"type":"PACKAGE","url":"https://github.com/metal3-io/ip-address-manager"}],"affected":[{"package":{"name":"github.com/metal3-io/ip-address-manager","ecosystem":"Go","purl":"pkg:golang/github.com/metal3-io/ip-address-manager"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.11.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-49pm-43hf-6xfq/GHSA-49pm-43hf-6xfq.json","last_known_affected_version_range":"\u003c= 1.11.6"}},{"package":{"name":"github.com/metal3-io/ip-address-manager","ecosystem":"Go","purl":"pkg:golang/github.com/metal3-io/ip-address-manager"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.12.0"},{"fixed":"1.12.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-49pm-43hf-6xfq/GHSA-49pm-43hf-6xfq.json","last_known_affected_version_range":"\u003c= 1.12.3"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N"}]}
