{"id":"GHSA-h5f8-crrq-4pw8","aliases":["GO-2025-3718"],"url":"https://o3.security/vulnerability/GHSA-h5f8-crrq-4pw8","summary":"Contrast workload secrets leak to logs on INFO level","details":"### Impact\n\nWhen the Contrast initializer is configured with a `CONTRAST_LOG_LEVEL` of `info` or `debug`, the workload secret is logged to `stderr` and written to Kubernetes logs. \n\nSince `info` is the default setting, this affects all Contrast installations that don't customize their initializers' log level.\n\nThe following audiences are **intended** to have access to workload secrets (see https://docs.edgeless.systems/contrast/1.7/architecture/secrets#workload-secrets):\n\n* Contrast Coordinator (can derive all workload secrets)\n* Contrast Initializer (obtains only the secret configured in the manifest)\n* Seedshare owner (can derive all workload secrets)\n* Workload owner (can update manifests to obtain secrets)\n\nThis vulnerability allows the following parties **unintended access** to workload secrets issued by a Coordinator:\n\n* Kubernetes users with `get` or `list` permission on `pods/logs`.\n* Others with read access to the Kubernetes log storage (most notably, the cloud provider).\n\nThis vulnerability **does not affect** scenarios where workload secrets are not used by the application (directly or with [secure persistence](https://docs.edgeless.systems/contrast/1.7/architecture/secrets#secure-persistence)). Applications designed for workload owner exclusion can't use workload secrets and are thus unaffected.\n\n### Patches\n\nN/A\n\n### Workarounds\n\nThis vulnerability can be mitigated by adding an environment variable `CONTRAST_LOG_LEVEL=warn` to the initializer after running `contrast generate`, and then running `contrast generate` again.\n\n### References\n\nN/A","published":"2025-05-28T14:40:25Z","modified":"2025-05-29T21:44:42.348457Z","cvss":{"score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/edgelesssys/contrast","fixedVersion":"1.8.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/edgelesssys/contrast/security/advisories/GHSA-h5f8-crrq-4pw8"},{"type":"PACKAGE","url":"https://github.com/edgelesssys/contrast"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2025-05-29T21:44:42.348457Z"}}
