{"cve":"CVE-2025-55196","nvd":{"published":"2025-08-13T23:15:27.500","modified":"2026-06-17T09:41:26.290","status":"Deferred","description":"External Secrets Operator is a Kubernetes operator that integrates external secret management systems. From version 0.15.0 to before 0.19.2, a vulnerability was discovered where the List() calls for Kubernetes Secret and SecretStore resources performed by the PushSecret controller did not apply a namespace selector. This flaw allowed an attacker to use label selectors to list and read secrets/secret-stores across the cluster, bypassing intended namespace restrictions. An attacker with the ability to create or update PushSecret resources and control SecretStore configurations could exploit this vulnerability to exfiltrate sensitive data from arbitrary namespaces. This could lead to full disclosure of Kubernetes secrets, including credentials, tokens, and other sensitive information stored in the cluster. This vulnerability has been patched in version 0.19.2. A workaround for this issue includes auditing and restricting RBAC permissions so that only trusted service accounts can create or update PushSecret and SecretStore resources.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-284"],"references":["https://github.com/external-secrets/external-secrets/commit/39cdba5863533007b582dc63dd300839326b2f1d","https://github.com/external-secrets/external-secrets/commit/de40e8f4fa9559c1d770bb674589b285da5ef2d1","https://github.com/external-secrets/external-secrets/pull/5109","https://github.com/external-secrets/external-secrets/pull/5133","https://github.com/external-secrets/external-secrets/security/advisories/GHSA-fcxq-v2r3-cc8h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2025-55196","score":0.0037,"percentile":0.30975,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fcxq-v2r3-cc8h","url":"https://osv.dev/vulnerability/GHSA-fcxq-v2r3-cc8h","summary":"External Secrets Operator's Missing Namespace Restriction Allows Unauthorized Secret Access","modified":"2025-08-18T13:57:17.878658Z","packages":[{"ecosystem":"Go","name":"github.com/external-secrets/external-secrets","purl":"pkg:golang/github.com/external-secrets/external-secrets","ranges":[">=0.15.0 <0.19.2"],"fixed":["0.19.2"]}]},{"id":"GO-2025-3885","url":"https://osv.dev/vulnerability/GO-2025-3885","summary":"External Secrets Operator's Missing Namespace Restriction Allows Unauthorized Secret Access in github.com/external-secrets/external-secrets","modified":"2025-08-18T13:57:17.878658Z","packages":[{"ecosystem":"Go","name":"github.com/external-secrets/external-secrets","purl":"pkg:golang/github.com/external-secrets/external-secrets","ranges":[">=0.15.0 <0.19.2"],"fixed":["0.19.2"]}]}],"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).
