goreleaser shows environment by default

GHSA-f6mm-5fc7-3g3c

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/goreleaser/goreleaser 1.26.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary Since #4787 the log output is printed on the INFO level, while previously it was logged on DEBUG. This means if the go build output is non-empty, goreleaser leaks the environment. PoC Create a Go project with dependencies, do not pull them yet (or run goreleaser later in a container, or delete $GOPATH/pkg). Make sure to have secrets set in the environment Make sure to not have go mod tidy in a before hook Run goreleaser release --clean Go prints lots of go: downloading ... lines, which triggers the "if output not empty, log it" line, which includes the environment. Impact Credentials and tokens are leaked.

# Patch Next advisory brief: GHSA-f6mm-5fc7-3g3c

Advisory: goreleaser shows environment by default
IDs: GHSA-f6mm-5fc7-3g3c
Record: https://patchnext.com/advisories/ghsa-f6mm-5fc7-3g3c (revision 1, source checked 26 Oct 2026, 15:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/goreleaser/goreleaser 1.26.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/goreleaser/goreleaser: affected >= 1.26.0, <= 1.26.0; fixed in 1.26.1

## Suggested inspection (read-only)
- Go github.com/goreleaser/goreleaser: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/goreleaser/goreleaser.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-f6mm-5fc7-3g3c (GitHub-reviewed advisory GHSA-f6mm-5fc7-3g3c lists affected ranges: Go github.com/goreleaser/goreleaser >=1.26.0 <=1.26.0)
