On October 22, 2026, goenvecho v1.4.2 was released. This is a security-focused rebuild with no functional code changes. The container image is rebuilt with Go 1.27.3 to distrust compromised eMudhra intermediate CAs referenced as GO-2026-6809 / CVE-2026-111943. For users, the release is a drop-in upgrade: behavior, API, and configuration remain identical to v1.4.1.

What’s new

  • Security rebuild: the published container image is built with the golang:1.27.3 builder instead of golang:1.27.1 to address the eMudhra CA trust issue. No Go source files were modified in this range.
  • No changes to application behavior. The GET response format, PORT environment variable, and optional PRETTY_PRINT flag are unchanged.
  • No new features or configuration options are introduced in v1.4.2.

Why it matters

goenvecho is used for debugging and testing container environments by exposing environment variables as JSON. Even though the application itself is unchanged, the toolchain used to build the binary matters for supply-chain trust. Rebuilding with Go 1.27.3 ensures the image no longer trusts the compromised eMudhra intermediate CAs, reducing risk for teams that pull and run the image in CI, staging, or local development.

Because there are no functional changes, existing deployments can be updated with confidence. The upgrade is safe and requires no configuration adjustments.

Upgrade

To pick up the security rebuild, update to the v1.4.2 container image from GitHub Packages. Pull the new tag and redeploy as you normally would. No environment variables, ports, or usage patterns change.
