Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The npm package git-diff is vulnerable in versions before 2.0.7. An attacker who can supply crafted strings to the gitDiff API can inject operating system commands, which run with the privileges of the Node.js process. Upgrade to git-diff 2.0.7 or later, which contains the fix.
