CVE-2026-45772

描述

### Impact 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. ### Fix Turbo now avoids executing project-local Yarn during package manager detection. Yarn versions and paths are inferred from metadata such as `package.json`, parsing the value of `yarnPath` in `.yarnrc.yml` rather than executing it, and `yarn.lock`, and unrecognized Yarn lockfile formats are rejected instead of falling back to executing `yarn`. ### Workarounds If you cannot upgrade immediately, do not run Turborepo commands in untrusted repositories. Review or remove `.yarnrc.yml` files that define `yarnPath` before running Turborepo, especially in CI or automated tooling that processes external projects.
