Prior to 0.21.10, the @backstage/plugin-kubernetes-backend package is affected by unsupported catalog cluster authentication mode in kubernetes backend. Deployments using catalog cluster discovery may be affected when catalog contributors can create or modify kubernetes-cluster Resource entities. With the required endpoint permissions and pod RBAC, the backend can use its local in-cluster identity, potentially exposing Kubernetes resources readable by that identity. The credential is used only with the local in-cluster API endpoint and is not sent to the catalog-supplied endpoint. This issue is fixed in version 0.21.10.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N","score":3.5,"severity":null}],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-h53x-hjx6-25gr","https://github.com/backstage/backstage/commit/c14f8be6908f0f719b16356e5492352311e28946","https://github.com/backstage/backstage/releases/tag/v1.54.6"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94005","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 6, 2026, 8:36:45 PM","dateUpdated":"Oct 9, 2026, 1:49:45 AM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
