Consul and related tools can misread '..' file paths
published 4 days ago
Summary
The Consul, etcd, step-cli, Traefik, and cosign-fips packages may handle file paths that include '..' (parent directory) incorrectly, potentially letting someone access or modify files they shouldn't. This could lead to data exposure or unintended changes on your system. Update each package to the newest release that fixes the path‑handling logic.

- Update cleanstart consul to version 1.22.7-r3.
- Update cleanstart etcd to version 3.6.14-r1.
- Update cleanstart step-cli to version 0.28.7-r4.
- Update cleanstart traefik to version 3.4.5-r1.
- Update cleanstart cosign-fips to version 2.5.3-r1.
- Update cleanstart cosign-fips to version 2.5.3-r2.
- Update cleanstart cosign-fips to version 2.5.3-r3.
- Update cleanstart cosign-fips to version 2.6.3-r3.
- Update cleanstart etcd to version 3.5.32-r2.
- Update cleanstart kyverno-policy-reporter-ui-fips to version 2.7.2-r2.
- Update cleanstart coredns-fips to version 1.14.7-r1.
- Update cleanstart cosign-fips to version 3.0.6-r2.
- Update cleanstart nats-server-config-reloader-fips to version 0.24.0-r1.
