CVE-2026-11572 Rich-Harris CVE debrief

CVE-2026-11572 is a high-severity vulnerability in the degit package. Versions before 2.8.6 and from 3.0.0 to before 3.3.1 are vulnerable to command injection due to improper sanitization of user input for git shell commands. This allows an attacker to execute arbitrary operating system commands as the process user by supplying a specially crafted git repository name.

Who should care

Developers and users of the degit package, especially those using versions before 2.8.6 or between 3.0.0 and 3.3.1, should be aware of this vulnerability and take steps to mitigate it.

Technical summary

The vulnerability exists in the _cloneWithGit() and fetchRefs() functions, which directly invoke git shell commands with user-input data without proper sanitization. This can be exploited by providing a malicious git repository name, allowing the execution of arbitrary system commands.
