Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored in`kubectl.kubernetes.io/last-applied-configuration` annotation. pull request #7139 introduced the ability to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the `kubectl.kubernetes.io/last-applied-configuration` annotation which includes full secret body. In order to view the cluster annotations via the Argo CD API, the user must have `clusters, get` RBAC access. **Note:** In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as in bearer-token auth, the contents might be very sensitive. The bug has been patched in versions 2.8.3, 2.7.14, and 2.6.15. Users are advised to upgrade. Users unable to upgrade should update/deploy cluster secret with `server-side-apply` flag which does not use or rely on `kubectl.kubernetes.io/last-applied-configuration` annotation. Note: annotation for existing secrets will require manual removal.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-09-07 23:15:00","updated_at":"2023-10-27 14:31:00"},"problem_types":["CWE-532"],"metrics":[],"references":[{"url":"https://github.com/argoproj/argo-cd/pull/7139","name":"https://github.com/argoproj/argo-cd/pull/7139","refsource":"MISC","tags":[],"title":"feat: support adding labels and annotations to cluster secret (#7115) by chetan-rns · Pull Request #7139 · argoproj/argo-cd · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-fwr2-64vr-xv9m","name":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-fwr2-64vr-xv9m","refsource":"MISC","tags":[],"title":"Cluster secret might leak in cluster details page · Advisory · argoproj/argo-cd · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/argoproj/argo-cd/commit/4b2e5b06bff2ffd8ed1970654ddd8e55fc4a41c4","name":"https://github.com/argoproj/argo-cd/commit/4b2e5b06bff2ffd8ed1970654ddd8e55fc4a41c4","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-fwr2-64vr-xv9m · argoproj/argo-cd@4b2e5b0 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-40029","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-40029","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"40029","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"linuxfoundation","cpe5":"argo_continuous_delivery","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"kubernetes","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-40029","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"Argo CD is a declarative continuous deployment for Kubernetes.
