Summary

Malicious code in rai6jaisahthaghee5ou-loader-package (npm)

Details

Source: amazon-inspector (6de53fbd264f685e033789fe5929c63f322366219d80707ec419a48a85e253c9)

The package's main module is an IIFE that injects a element pointing at the hardcoded URL https://nee1ahnaw7.xsses.link and appends it to the document, causing whatever JavaScript that host serves to execute in the caller's page context. The destination is unpinned, opaque, unrelated to the package's declared identity or publisher, and the host name aligns with XSS/payload delivery infrastructure. Any application that bundles this dependency will fetch and execute attacker-controlled JavaScript at runtime, granting full code execution within the app's origin — enabling credential/session theft, arbitrary DOM manipulation, and further payload staging.

CWE

CWE-506 - The product contains code that appears to be malicious in nature.
