CVE-2026-94185Public exploitHinoki check available

File disclosure via alias path traversal

Published Sep 21, 2026 · Updated Sep 21, 2026

Path traversal in nvm 0.40.7 and earlier allows context-dependent attackers to read local files via a crafted .nvmrc value. The nvm_alias function concatenates an unchecked alias onto $NVM_DIR/alias, and nvm_print_alias_file emits noncomment lines from the escaped path. Exploitation requires a user to run an nvm command in an attacker-supplied repository, exposing the first meaningful line of any file readable by that user; a directly supplied traversing alias exposes every meaningful line.
