CVE-2026-10796

nvm (Node Version Manager) through 0.40.4 executes arbitrary commands from version strings supplied by the configured Node.js/io.js mirror. Commands such as `nvm install` read the available versions from the mirror's index.tab and use the selected version, without sanitization, to build download URLs and shell/awk commands. Two sinks are affected by the same untrusted input: nvm_download() built a curl/wget command string and ran it with `eval`, so a version field containing command substitution
