sbt: Source dependency feature (via crafted VCS URL) leads to arbitrary code execution on Windows
Summary
On Windows, sbt uses Process("cmd", "/c", ...) to run VCS commands (git, hg, svn). The URI fragment (branch, tag, revision) is user-controlled via the build definition and passed to these commands without validation. Because cmd /c interprets &, |, and ; as command separators, a malicious fragment can execute arbitrary commands.
Patched version
Technically, sbt 1.12.7 is patched, but it has a bug that makes source dependency non-functional, so update to sbt 1.12.8 or later instead.

)Impact
Windows users are impacted. An attacker can execute arbitrary Windows commands if they control the dependency URI.
