{"cve":"CVE-2023-23947","nvd":{"published":"2023-02-16T18:15:11.310","modified":"2026-06-17T05:38:20.940","status":"Modified","description":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All Argo CD versions starting with 2.3.0-rc1 and prior to 2.3.17, 2.4.23  2.5.11, and 2.6.2 are vulnerable to an improper authorization bug which allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters). A patch for this vulnerability has been released in Argo CD versions 2.6.2, 2.5.11, 2.4.23, and 2.3.17. Two workarounds are available. Either modify the RBAC configuration to completely revoke all `clusters, update` access, or use the `destinations` and `clusterResourceWhitelist` fields to apply similar restrictions as the `namespaces` and `clusterResources` fields.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.5},"cwes":["CWE-863"],"references":["https://github.com/argoproj/argo-cd/commit/fbb0b99b1ac3361b253052bd30259fa43a520945","https://github.com/argoproj/argo-cd/security/advisories/GHSA-3jfq-742w-xg8j","https://github.com/argoproj/argo-cd/commit/fbb0b99b1ac3361b253052bd30259fa43a520945","https://github.com/argoproj/argo-cd/security/advisories/GHSA-3jfq-742w-xg8j"],"products":["argoproj:argo_cd"],"source":"nvd","synced_at":"2026-10-19T21:37:38.595364862+00:00"},"epss":{"cve":"CVE-2023-23947","score":0.00671,"percentile":0.52049,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3jfq-742w-xg8j","url":"https://osv.dev/vulnerability/GHSA-3jfq-742w-xg8j","summary":"Users with any cluster secret update access may update out-of-bounds cluster secrets","modified":"2026-09-10T03:49:56.567420152Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=2.3.0 <2.3.17"],"fixed":["2.3.17"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=2.4.0 <2.4.23"],"fixed":["2.4.23"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=2.5.0 <2.5.11"],"fixed":["2.5.11"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=2.6.0 <2.6.2"],"fixed":["2.6.2"]}]},{"id":"GO-2023-1577","url":"https://osv.dev/vulnerability/GO-2023-1577","summary":"Users with any cluster secret update access may update out-of-bounds cluster secrets in github.com/argoproj/argo-cd","modified":"2026-03-03T04:53:22.602654Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.3.0 <2.3.17",">=2.4.0 <2.4.23",">=2.5.0 <2.5.11",">=2.6.0 <2.6.2"],"fixed":["2.3.17","2.4.23","2.5.11","2.6.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
