Vulnerability from github – Published: 2025-11-20 18:31 – Updated: 2025-11-21 18:01

Summary

zx Uses Incorrectly-Resolved Name or Reference

Details

When zx is invoked with --prefer-local=, the CLI creates a symlink named ./node_modules pointing to /node_modules. Due to a logic error in src/cli.ts (linkNodeModules / cleanup), the function returns the target path instead of the alias (symlink path). The later cleanup routine removes what it received, which deletes the target directory itself. Result: zx can delete an external /node_modules outside the current working directory.

Severity

5.6 (Medium)

CVE-2025-13437 (GCVE-0-2025-13437)

Vulnerability from cvelistv5 – Published: 2025-11-20 16:25 – Updated: 2025-11-20 16:49

Title

Arbitrary node_modules Directory Deletion in Google zx

Summary

When zx is invoked with --prefer-local=<path>, the CLI creates a symlink named ./node_modules pointing to <path>/node_modules. Due to a logic error in src/cli.ts (linkNodeModules / cleanup), the function returns the target path instead of the alias (symlink path). The later cleanup routine removes what it received, which deletes the target directory itself. Result: zx can delete an external <path>/node_modules outside the current working directory.
