GHSA-v5rq-49vh-5v5c: @simple-git/argv-parser (CVE-2026-102829)

Package	Ecosystem	Affected	Fixed in
@simple-git/argv-parser	npm	<2.0.1	2.0.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

@simple-git/argv-parser versions before 2.0.1 do not treat the VISUAL environment variable as an unsafe editor setting, so the default guard allows it. An attacker who can influence environment values that an application passes to Git could cause Git to run an attacker-chosen program when an editor opens, such as during commit --amend. Upgrade to version 2.0.1 or later.
