Overview
Affected versions of this package are vulnerable to Command Injection via the prepareEnv function in parse-env.ts, which fails to recognize the VISUAL environment variable as a tracked unsafe editor key. Because VISUAL is not included in the GitEnvKeys map, it is silently discarded before collectConfigVulnerabilities inspects the environment, allowing an attacker-controlled VISUAL value to bypass the blockUnsafeOperationsPlugin spawn guard that would otherwise require the consumer to explicitly opt in to allowUnsafeEditor. This bypass permits an attacker who can influence the process environment to inject an arbitrary editor binary, potentially achieving remote code execution.
