Security releases available

Updates are now available for the 18.x, 20.x, 21.x Node.js release lines for the following issues.

Command injection via args parameter of child_process.spawn without shell option enabled on Windows (CVE-2024-27980) - (HIGH)

Due to the improper handling of batch files in child_process.spawn / child_process.spawnSync, a malicious command line argument can inject arbitrary commands and achieve code execution even if the shell option is not enabled.

It is important to note that there has been a breaking change for Windows users who utilize child_process.spawn and child_process.spawnSync. Node.js will now error with EINVAL if a .bat or .cmd file is passed to child_process.spawn and child_process.spawnSync without the shell option set. If the input to spawn/spawnSync is sanitized, users can now pass { shell: true } as an option to prevent the occurrence of EINVALs errors.

While it is possible to also pass --security-revert=CVE-2024-27980 to revert the security patch, we strongly advise against doing so. Impact:

  • This vulnerability affects all Windows users in active release lines: 18.x, 20.x, 21.x
