CVE-2026-32948: sbt: Source dependency feature (via crafted VCS URL) leads to arbitrary code execution on Windows

• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-03-24 · updated 2026-06-17
• Weakness: CWE-78

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.

Affected products

• sbt: from 0.9.5 before 1.12.7 — fixed in 1.12.7

How to fix

Upgrade to a fixed version: sbt 1.12.7. Check the vendor advisory for mitigations.
