Details

ZX Allows Environment Variable Injection for dotenv API ### Impact This vulnerability is an **Environment Variable Injection** issue in `dotenv.stringify`, affecting `google/zx` version **8.3.1**. An attacker with control over environment variable values can inject unintended environment variables into `process.env`. This can lead to **arbitrary command execution** or **unexpected behavior** in applications that rely on environment variables for security-sensitive operations. Applications that process untrusted input and pass it through `dotenv.stringify` are particularly vulnerable. ### Patches This issue has been **patched** in version **8.3.2**. Users should **immediately upgrade** to this version to mitigate the vulnerability. ### Workarounds If upgrading is not feasible, users can mitigate the vulnerability by **sanitizing user-controlled environment variable values** before passing them to `dotenv.stringify`. Specifically, avoid using `"`, `'`, and backticks in values, or enforce strict validation of environment variables before usage. ### References - [Issue Report](https://github.com/google/zx/issues/) - [Security Policy](https://github.com/google/zx/security/policy) - [Google Vulnerability Disclosure](https://g.co/vulnz) - [Patch](https://github.com/google/zx/pull/1094)
