{"id":"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","aliases":["CVE-2025-71425","GO-2025-3718"],"modified":"2026-09-27T11:55:47.067562466Z","published":"2025-05-28T14:40:25Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2025-05-28T14:40:25Z","nvd_published_at":null,"cwe_ids":["CWE-532"]},"references":[{"type":"WEB","url":"https://github.com/edgelesssys/contrast/security/advisories/GHSA-h5f8-crrq-4pw8"},{"type":"PACKAGE","url":"https://github.com/edgelesssys/contrast"}],"affected":[{"package":{"name":"github.com/edgelesssys/contrast","ecosystem":"Go","purl":"pkg:golang/github.com/edgelesssys/contrast"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.8.1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 1.8.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/05/GHSA-h5f8-crrq-4pw8/GHSA-h5f8-crrq-4pw8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
