PatchTheCVECVE-2026-44705: tmp is a temporary file and directory creator for node.js
CVE-2026-44705 is a high-severity flaw (CVSS 8.2) affecting tmp. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
tmp is a temporary file and directory creator for node.js. Prior to 0.2.6, the tmp npm package contains a path traversal vulnerability that allows escaping the intended temporary directory when untrusted data flows into the prefix, postfix, or dir options. By embedding traversal sequences (e.g., ../) or path separators in these parameters, attackers can cause files to be created outside the configured temporary base directory at attacker-controll
