NVD description

simple-git, an interface for running git commands in any node.js application, enables applications to execute Git operations from JavaScript. Prior to 4.0.0, the default blockUnsafeOperationsPlugin compares parsed option names with literal dangerous option spellings while Git accepts unambiguous long-option abbreviations. Attacker-influenced push arguments such as abbreviated --receive-pack or --exec forms can therefore bypass detectVulnerableFlags, reach git push against a local or file remote or an attacker-influenced receive-pack target, and cause Git to invoke an attacker-selected command in consumers that expose those arguments. The clone-side abbreviation handling does not protect the push path. This issue is fixed in 4.0.0.

    🚨HIGH - simple-git push arg filter bypass via long-option abbreviations (CVE-2026-102827) In simple-git <4.0.0, the default blockUnsafeOperationsPlugin only matches full dangerous option spellings, but Git accepts unambiguous long-option abbreviations. Attacker-supplied abbreviated push args (e.g., --rece/--exe for --receive-pack/--exec) can bypass checks and make git invoke an attacker-chosen command when apps pass through push arguments. 👉Affected: simple-git < 4.0.0 | Upgrade to 4.0.0
