OpenSSF/OSV advisory MAL-2026-13792 confirms this npm version as malicious. Package chmjdsidwlf5@1.0.0 contains 2 files with no a static rule matches and no traced behavior indicating exfiltration, install-time remote code execution, silent relay, credential distribution, backdoor, or self-propagation. The random-looking package name is unusual, but name shape alone is not a threat and the code performs no installer-facing harmful action.
