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-2026-16413/ (Markdown: https://insights.sbomify.com/MAL-2026-16413/index.md)","id":"MAL-2026-16413","markdown":"https://insights.sbomify.com/MAL-2026-16413/index.md","name":"MAL-2026-16413","record":{"aliases":["GHSA-8g69-976g-h44g"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"@tvg-mar/promos-gtm@9.9.10 executes an out-of-band DNS exfiltration routine both at install time (via a scripts.install hook running node index.js) and on require() (top-level module load chain reaching runtime/support/telemetry/probe/impl.js). The probe reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a timestamp and a prefix tag, and issues dns.resolve4 against a subdomain of a hardcoded attacker-controlled domain. The destination suffix (oob.algamil7x.xyz), prefix tag (tvggtm), Node built-in names (os, dns, process, userInfo, hostname, cwd, resolve4), and the internal _load API are stored as hex character-code arrays and reassembled at runtime via String.fromCharCode; the os and dns modules are loaded indirectly through module.constructor._load to further hide the behavior. The DNS channel bypasses typical HTTP egress controls and delivers installer host identifiers to attacker infrastructure with no relation to the package's advertised purpose.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
