CONSUL AND DATAPLANE 2.0 SHIP WITH CRITICAL CRYPTO PATCHES

By RepoJournal · Filed · About HashiCorp

HashiCorp shipped major versions across Consul, Consul-K8s, and Consul Dataplane overnight, all patching the same cryptographic vulnerabilities that hit the Go ecosystem this spring.

Consul v2.0.0 [2] and Consul Dataplane v2.0.0 [1] both land with mandatory upgrades to golang.org/x/crypto and golang.org/x/net, closing the CVEs that forced every Go shop to scramble weeks ago. Consul-K8s follows suit [3] with the same dependency chain remediation across all modules, replacing go-jose/v3 with v4 to fix GHSA-c5q2-7r4c-mv6g. The dataplane release also bumps the UBI base image to 9.8 [1] and suppresses spurious OSV scanner false positives in RHEL RPM paths [4], which matters if you're running supply chain scanning in production. On the breaking changes front: Consul 2.0 increases default HTTP timeouts from 30 seconds to 15 minutes [2], a significant shift for long-polling blocking queries that could affect your connection pooling assumptions. Envoy gets pinned to 1.37.2 and Go to 1.26 [2], so you're looking at a coordinated upgrade across your entire service mesh.
