Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2026-44244)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to improper input validation in GitConfigParser.set_value() when writing user-supplied configuration values to .git/config. A local user can inject newline characters to create a malicious core.hooksPath setting and execute arbitrary code.

Any Git operation that invokes hooks, such as commit, merge, or checkout, may trigger execution from the attacker-controlled path. In shared repositories, the injected configuration can persist and affect subsequent Git operations by other users.
