ZX Allows Environment Variable Injection for dotenv API
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
