It is named `local` inside the list of clusters in the Rancher UI.\n\nStandard users could leverage their existing permissions to manipulate Kubernetes secrets in the `local` cluster, resulting in the secret being deleted, but their read-level permissions to the secret being preserved. When this operation was followed-up by other specially crafted commands, it could result in the user gaining access to tokens belonging to service accounts in the `local` cluster.\n\nUsers that have custom global roles which grant `create` and `delete` permissions on `secrets` would also be able to exploit this vulnerability.\n\nUsers with [audit logs enabled](https://ranchermanager.docs.rancher.com/how-to-guides/advanced-user-guides/enable-api-audit-log#enabling-api-audit-log) in Rancher can try to identify possible abuses of this issue by going through the logs. To sieve through the data filter by `kind: Secret` with `type: provisioning.cattle.io/cloud-credential`, then investigate all log entries that affect that specific resource. A secondary check would be to filter by all operations with `Opaque` Secrets within the `cattle-global-data` namespace.\n\nAfter patching, it is recommended that users review access methods to Rancher (including RBAC policies, tokens, and host-level node access), to ensure that no changes were made to persist access to users who have leveraged this vulnerability.\n\n### Patches\n\nPatched versions include releases `2.6.13`, `2.7.4` and later versions. \n\n### Workarounds\n\nThere is no direct mitigation besides updating Rancher to a patched version.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n- Open an issue in the [Rancher](https://github.com/rancher/rancher/issues/new/choose) repository.\n- Verify with our [support matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/).","state":0,"publishedAt":"2023-06-06T02:00:28+00:00","modifiedAt":"2026-07-08T06:52:56.7909882+00:00","affected":[{"ecosystem":"Go","name":"github.com/rancher/rancher","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.6.0"},{"kind":"fixed","version":"2.6.13"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/rancher/rancher","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.7.0"},{"kind":"fixed","version":"2.7.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/rancher/rancher/security/advisories/GHSA-p976-h52c-26p6","https://nvd.nist.gov/vuln/detail/CVE-2023-22647","https://bugzilla.suse.com/show_bug.cgi?id=CVE-2023-22647","https://github.com/rancher/rancher","https://github.com/rancher/rancher/releases/tag/v2.6.13","https://github.com/rancher/rancher/releases/tag/v2.7.4"],"sourceUrl":"https://github.com/advisories/GHSA-p976-h52c-26p6","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-p976-h52c-26p6","identifiers":["GHSA-p976-h52c-26p6","CVE-2023-22647"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
