CVE-2025-71423
highpriority · track · 29EPSS 0.002 · 11 %ileUSEPSS · scored 2026-10-27
Edgelesssys Contrast is a confidential-computing runtime for Kubernetes. In versions 1.9.0 before 1.12.2, the initializer logs the full NewMeshCert response — which contains the workload secret — to standard output at INFO level. As a result, workload secrets are exposed to any Kubernetes user with get or list permission on pods/logs. Because workload secrets are used for encrypted storage and Vault integration, those must also be considered compromised. This is a regression of GHSA-h5f8-crrq-4pw8.

- GHSA-vxg3-w9rv-rhr2Contrast leaks workload secrets to logs on INFO level2025-08-28ghsa · osvUS
This is the same vulnerability as https://github.com/edgelesssys/contrast/security/advisories/GHSA-h5f8-crrq-4pw8. The original vulnerability had been fixed for release `v1.8.1`, but the fix was not ported to the main branch and thus not present in releases `v1.9.0` ff. Below is a brief repetition of the relevant sections from the first GHSA, where you can find the full details. ### Impact * [Workload secrets](https://docs.edgeless.systems/contrast/1.11/architecture/secrets#workload-secrets) are visible to Kubernetes users with `get` or `list` permission on `pods/logs`, and thus need to be considered compromised. * Since workload secrets are used for [encrypted storage](https://docs.edgeless.systems/contrast/1.11/howto/encrypted-storage) and [Vault integration](https://docs.edgeless.systems/contrast/1.11/howto/vault), those need to be considered compromised, too. ### Patches Patches: * https://github.com/edgelesssys/contrast/commit/5a5512c4af63c17bb66331e7bd2768a863b2f225 * https://github.com/edgelesssys/contrast/commit/cf58026b30c43fe7df91eac5322da02e1725d554 The patches are released with `v1.12.2` and `v1.13.0` (not yet published). Since the secrets are compromised, Contrast needs to be initialized from scratch. ### Workarounds Existing workload secrets are compromised. The Contrast cluster needs to be newly initialized, and logging needs to be turned off. ### References First occurrence: * https://github.com/edgelesssys/contrast/security/advisories/GHSA-h5f8-crrq-4pw8 We are defining a process for handling GHSAs that should prevent such regressions in the future: * https://github.com/edgelesssys/contrast/pull/1739
