CVE-2026-28291: simple-git Affected by Command Execution via Option-Parsing Bypass

simple-git enables running native Git commands from JavaScript. Some commands accept options that allow executing another command; because this is very dangerous, execution is denied unless the user explicitly allows it. This vulnerability allows a malicious actor who can control the options to execute other commands even in a “safe” state where the user has not explicitly allowed them. The vulnerability was introduced by an incorrect patch for CVE-2022-25860. It is likely to affect all versions prior to and including 3.28.0.
