CVE-2026-32948
Received Received - Intake
Command Injection in sbt VCS URI Handling on Windows

Publication date: 2026-03-24

Last updated on: 2026-03-26

Assigner: GitHub, Inc.

Description
sbt is a build tool for Scala, Java, and others. From version 0.9.5 to before version 1.12.7, 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. This issue has been patched in version 1.12.7.

Executive Summary

This vulnerability exists in sbt, a build tool for Scala, Java, and others, specifically on Windows versions from 0.9.5 to before 1.12.7. sbt uses the Windows command processor (cmd /c) to run version control system (VCS) commands like git, hg, and svn. The problem arises because the URI fragment (such as branch, tag, or revision), which is user-controlled via the build definition, is passed directly to these commands without any validation.

Since cmd /c interprets special characters like &, |, and ; as command separators, a maliciously crafted URI fragment can inject and execute arbitrary commands on the system. This means an attacker can run unintended commands by exploiting this flaw.

This issue was fixed in sbt version 1.12.7.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary commands on your Windows system when using vulnerable versions of sbt. Because the user-controlled URI fragment is passed without validation to the command line, an attacker could inject malicious commands that the system would execute.

The impact includes potential unauthorized actions such as modifying files, installing malware, or compromising the system's integrity and confidentiality.
