AI-suggested

Upgrade nvm to version 0.41.0 or later, where the authorization header is no longer passed as a command-line argument but via stdin or a private config file, preventing token exposure. If upgrading is not immediately possible, avoid setting NVM_AUTH_HEADER on shared hosts or ensure /proc is mounted with hidepid= to restrict process argument visibility. Note that BusyBox wget does not support the private config file mitigation, so using curl or GNU Wget is recommended.

Description

Node Version Manager (nvm) versions 0.40.0 through 0.40.8 have a vulnerability where the authorization header set in NVM_AUTH_HEADER is passed as a visible command-line argument to curl or wget during downloads. This exposure allows other local users on the same machine to potentially read sensitive tokens via process listings. The issue is fixed in version 0.41.0, which changes the method of passing the header to avoid command-line exposure.
