Malicious code in @uh-platform/webcard (npm)
Details
**Severity:** Critical **Affected versions:** `= 99.0.0` ## Source: amazon-inspector (2b9f7c250a563ff0915cbcdb1e2fa8a402094c030d7223a726c69ffea6de4b8c) @uh-platform/[email protected] declares a preinstall hook that runs index.js, which shells out to curl against a unique Burp Collaborator subdomain at http://pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/. This fires unconditionally on npm install and confirms code execution and DNS/HTTP callback from the installer's host to an attacker-controlled out-of-band collector. The package version is 99.0.0 under an org scope with a self-referential dependency on @uh-platform/[email protected] and a redacted SDK description, matching the canonical dependency-confusion shape aimed at hijacking resolution of an internal scoped package name. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/6926bf8bfadfccf9e5be36eafde008a2b17caf3e/osv/malicious/npm/@uh-platform/webcard/MAL-2026-16362.json)) **References:** - https://github.com/ossf/malicious-packages/blob/6926bf8bfadfccf9e5be36eafde008a2b17caf3e/osv/malicious/npm/@uh-platform/webcard/MAL-2026-16362.json - https://www.npmjs.com/package/@uh-platform/webcard/v/99.0.0 - https://github.com/advisories/GHSA-5h99-j25f-5q62
