Some of these +commands take arbitrary input, either provided by users or fetched from +external sources. To prevent potential command injection vulnerabilities +or misinterpretation of arguments as flags, this change updates the VCS +commands to use various techniques to separate flags from positional +arguments, and to directly associate flags with their values. + +Additionally, we update the environment variable for Mercurial to use +`HGPLAIN=+strictflags`, which is the more explicit way to disable user +configurations (intended or otherwise) that might interfere with command +execution. + +We also now disallow version strings from being prefixed with '-' or +'/', as doing so opens us up to making the same mistake again in the +future. As far as we know there are currently ~0 public modules affected +by this. + +While I was working on cmd/go/internal/vcs, I also noticed that a +significant portion of the commands being implemented were dead code. +In order to reduce the maintenance burden and surface area for potential +issues, I removed the dead code for unused commands. + +We should probably follow up with a more structured change to make it +harder to accidentally re-introduce these issues in the future, but for +now this addresses the issue at hand. + +Thanks to splitline (@splitline) from DEVCORE Research Team for +reporting this issue. + +Fixes CVE-2025-68119 +Updates #77099 +Fixes #77103 + +CVE: CVE-2025-68119 +Upstream-Status: Backport [https://github.com/golang/go/commit/73fe85f0ea1b] + +Backport Changes: +- In file src/cmd/go/internal/modfetch/codehost/git.go, Replaced the + function call runGIT with RUN.
