Vulnerability from github – Published: 2026-03-13 20:57 – Updated: 2026-03-16 17:08

Summary

@google/clasp vulnerable to unsafe path traversal cloning or pulling a malicious script

Details

Impact

Allows an attacker to perform a "Path Traversal" attack to modify files outside the projects directory, potentially allowing for running attacker code on the developer's machine.

Patches

Fixed in version 3.2.0

Workarounds

Only clone or pull scripts from trusted sources
Review the output of the pull and clone commands to verify only expected project files are modified

Severity

8.7 (High)
