CVE-2026-46412Known exploitationNetwork attack vector

Credential theft via malicious postinstall script

Published Jul 20, 2026 · Updated Jul 20, 2026

Embedded malicious code in BeProduct @beproduct/nestjs-auth 0.1.2 through 0.1.19 allows attackers to steal installation-host credentials. A postinstall script reads npm, GitHub, AWS, Vault, and environment secrets, exfiltrates them to getsession.org, and writes IDE-hook persistence files. Installing an affected release executes the payload automatically with the installer account's access, exposing credentials and modifying the working tree.
