Impacted is an unknown function. Executing a manipulation can lead to os command injection. This vulnerability appears as CVE-2026-28291. The attack may be performed from remote. There is no available exploit. Upgrading the affected component is recommended. Detailsinfo A vulnerability was found in steveukx git-js up to 3.31.x. It has been declared as critical. This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes: simple-git enables running native Git commands from JavaScript. Versions up to and including 3.31.1 allow execution of arbitrary commands through Git option manipulation, bypassing safety checks meant to block dangerous options like -u and --upload-pack. The flaw stems from an incomplete fix for CVE-2022-25860, as Git's flexible option parsing allows numerous character combinations (e.g., -vu, -4u, -nu) to circumvent the regular-expression-based blocklist in the unsafe operations plugin. Due to the virtually infinite number of valid option variants that Git accepts, a complete blocklist-based mitigation may be infeasible without fully emulating Git's option parsing behavior. This issue has been fixed in version 3.32.0. The advisory is shared for download at github.com. This vulnerability was named CVE-2026-28291 since 02/26/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1202. Upgrading to version 3.32.0 eliminates this vulnerability. The upgrade is hosted for download at github.com.
