CVE-2026-45772
From 1.1.0 to before 2.9.14, Turborepo can be vulnerable to arbitrary code execution when run in untrusted repositories that contain malicious Yarn configuration.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
Description
Turborepo is a high-performance build system for JavaScript and TypeScript codebases. From 1.1.0 to before 2.9.14, Turborepo can be vulnerable to arbitrary code execution when run in untrusted repositories that contain malicious Yarn configuration. In affected versions, package manager detection executed yarn --version from the project directory, which could cause Yarn to load and execute a project-controlled yarnPath from .yarnrc.yml. An attacker who controls repository contents could cause code execution when a user or CI system runs affected turbo, @turbo/codemod, or @turbo/workspace conversion commands. This vulnerability is fixed in 2.9.14.
