Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-16370/ (Markdown: https://insights.sbomify.com/MAL-2026-16370/index.md)","id":"MAL-2026-16370","markdown":"https://insights.sbomify.com/MAL-2026-16370/index.md","name":"MAL-2026-16370","record":{"aliases":["GHSA-mx57-mmpv-mwjr"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"@uol-afiliados/affiliated-config-lib@102.0.0 declares a preinstall hook (`node index.js`) that shells out via `require('child_process').exec` to run `curl` against a subdomain of `hqbv58hgt1sjk7vf7ru4o0mwzn5etahz.oastify.com` (Burp Collaborator out-of-band interaction infrastructure). The subdomain is constructed with shell command substitution `$(hostname).$(whoami)`, so the installer's host name and current user name are embedded in the DNS/HTTP request and sent to the attacker-controlled collector automatically on `npm install`. The package ships no legitimate functionality — the sole install-time effect is host/user identifier exfiltration. The scoped name `@uol-afiliados/*` mimics an internal organization namespace, consistent with dependency-confusion reconnaissance.\n\nAny computer that has this package installed or running should be considered fully compromised.
