CVE-2026-28291: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in steveukx git-js
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.
AI Analysis
Technical Summary
The vulnerability in steveukx git-js (simple-git) versions prior to 3.32.0 allows arbitrary command execution through manipulation of Git command options. The root cause is the incomplete mitigation of a prior vulnerability, where the blocklist approach to filter dangerous Git options is circumvented by Git's acceptance of numerous valid option combinations. Because Git's option parsing is highly flexible, the blocklist cannot comprehensively prevent all unsafe options without fully emulating Git's parsing logic. This flaw enables OS command injection, impacting confidentiality, integrity, and availability of affected systems. The issue is fixed in version 3.32.0.
Potential Impact
Successful exploitation can lead to remote execution of arbitrary OS commands without privileges or user interaction, resulting in full compromise of the affected system's confidentiality, integrity, and availability. The vulnerability affects all versions of git-js before 3.32.0. No known active exploits have been reported.
Mitigation Recommendations
Upgrade to git-js version 3.32.0 or later, where this vulnerability has been fixed. Since this is a client-side library, applying the official fix by updating the dependency is the recommended remediation. Patch status is confirmed by the vendor's versioning information. No additional mitigations are indicated.
