Name of the Vulnerable Software and Affected Versions Turborepo versions 1.1.0 through 2.9.13

Description Turborepo is a high-performance build system for JavaScript and TypeScript codebases. A flaw in package manager detection allows arbitrary code execution when the system is run in untrusted repositories containing malicious Yarn configuration. The issue occurs because the system executes yarn --version from the project directory, which can lead Yarn to load and execute a project-controlled yarnPath defined in the .yarnrc.yml file. This can be triggered when a user or CI system runs turbo, @turbo/codemod, or @turbo/workspace conversion commands.

Recommendations Update to version 2.9.14.
