MAL-2026-13491 Malicious code in rdfxvela (npm)

cli.js embeds a base64-encoded RSA private key in CONFIG.encodedSSHKey. When the user invokes any rx subcommand (signup/login/list/download/deploy), the CLI writes the decoded key to a temp file at mode 0600 and runs ssh -o StrictHostKeyChecking=no -i <key> [email protected] "<cmd>" against the author's signing server. Every recipient of the tarball receives the same key and can log in as ubuntu on 79.72.65.161. Separately, user-entered passwords are interpolated unescaped into the remote shell command line (bash.../auth.sh signup ${username} ${password}), exposing them in remote process argv and logs. There are no install-time or import-time lifecycle hooks, no reads of installer secrets or environment variables, no exfiltration of installer-owned data, and no fetching or execution of remote code on the installer's machine. The shared credential authorizes access to a host owned by the package author; the blast radius is confined to the author's own infrastructure.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
