Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Go before 1.8.4 and 1.9.x before 1.9.1 allows "go get" remote command execution. Using custom domains, it is possible to arrange things so that example.com/pkg1 points to a Subversion repository but example.com/pkg1/pkg2 points to a Git repository. If the Subversion repository includes a Git checkout in its pkg2 directory and some other work is done to ensure the proper ordering of operations, "go get" can be tricked into reusing this Git checkout for the fetch of code from pkg2. If the Subversion repository's Git checkout has malicious commands in .git/hooks/, they will execute on the system running "go get."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Go 1.8.4 or Go 1.9.1 or later (recommended: latest stable Go release)

  1. 1. Check current Go version by running: go version
  2. 2. Download the fixed Go version (1.8.4, 1.9.1, or newer stable release) from https://go.dev/dl/
  3. 3. Install the new Go version following the official installation guide for your operating system
  4. 4. Verify the installation by running: go version
  5. 5. Ensure the new Go binary is in your PATH and takes precedence over any older versions
  6. 6. Clean any cached packages that may have been fetched with the vulnerable version: go clean -modcache
Caveat Go 1.9 introduced some breaking changes from 1.8; review the Go 1.9 release notes for any compatibility concerns relevant to your codebase
