The npm package int_sezzle_sfra version 25.2.1 contains malicious code that executes automatically during installation. It collects sensitive host information such as hostname, OS details, user identity, and shell command outputs, then sends this data to an attacker-controlled external server. The package name mimics a legitimate Salesforce Commerce Cloud cartridge, indicating a dependency confusion attack. This results in unconsented data exfiltration from the installer's environment.
