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-2026-12767/ (Markdown: https://insights.sbomify.com/MAL-2026-12767/index.md)","id":"MAL-2026-12767","markdown":"https://insights.sbomify.com/MAL-2026-12767/index.md","name":"MAL-2026-12767","record":{"aliases":["GHSA-9hjp-75c7-rgxr"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require of the package, index.js loads _bridge.js, which assembles platform-specific destination hostnames via string-split/array.join obfuscation and downloads an opaque binary over HTTPS from Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev) with a DNS-TXT chunked fallback channel (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru).
