Prior to 2.4.1, a user who only has permission to create ExternalSecret resources can cause the operator to create a Secret that Kubernetes will automatically populate with a long-lived token for the specified service account. This effectively allows the user to impersonate any service account in the namespace without needing direct create permissions on TokenRequest or Secrets of that type. This vulnerability is fixed in 2.4.1.","state":0,"publishedAt":"2026-05-11T20:25:44.307+00:00","modifiedAt":"2026-06-17T10:48:32.953+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N","score":4.9,"severity":"MEDIUM"}],"references":["https://github.com/external-secrets/external-secrets/commit/4ddd240af7fe88725d9857b9a0c198073502e288","https://github.com/external-secrets/external-secrets/releases/tag/v2.4.1","https://github.com/external-secrets/external-secrets/security/advisories/GHSA-fq7h-9x26-6j22"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-42876","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-285"],"productCriteria":[],"sourceDates":{"published":"2026-05-11T20:25:44.307","lastModified":"2026-06-17T10:48:32.953"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
