A version string taken from an untrusted .nvmrc reaches this path, so a developer who runs `nvm use`, `nvm install`, or `nvm which` inside an attacker-supplied repository discloses the first non-comment line of an arbitrary file readable by that user, in the resulting \"is not yet installed\" error message. A user-supplied `nvm alias <traversing-name>` discloses every non-comment line of the target file. There is no integrity or availability impact, and no command execution on this path.",
