CONSUL-K8S PATCHES CRITICAL GO VULNERABILITY, RESTORES TEST SUITE
By RepoJournal · Filed · About HashiCorp
Consul-K8s shipped a critical security fix for CVE GO-2026-4918 overnight while simultaneously restoring unit tests that had vanished from the main branch.
The golang.org/x/net dependency got upgraded to v0.53.0 to patch the vulnerability [1][2], a move that closes a known attack surface in any K8s deployment running Consul. Separately, the sync-catalog command test suite that had been stripped from main is now restored and passing [3]—a clean bill of health for a component critical to service mesh synchronization. Meanwhile, the team is moving forward on API Gateway enhancements: SDS support is now available at multiple override levels (default, listener, service route) with a new RouteTLSSdsFilter CRD [4], and scaling logic for the custom gateway rolled in [5], though that PR still needs test coverage and changelog documentation before merge. On the tooling side, VSCode Terraform bumped its GitHub Actions dependency [6], a routine maintenance item with no breaking changes for users.
