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-2026-5791/ (Markdown: https://insights.sbomify.com/MAL-2026-5791/index.md)","id":"MAL-2026-5791","markdown":"https://insights.sbomify.com/MAL-2026-5791/index.md","name":"MAL-2026-5791","record":{"aliases":["GHSA-75f4-4w6r-vvch"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require('mddriver'), an IIFE in index.js invokes loadTokenData(), which fetches https://www.jsonkeeper.com/b/C4H0M (stored base64-encoded as \"aHR0cHM6Ly93d3cuanNvbmtlZXBlci5jb20vYi9DNEgwTQ==\" and decoded with atob), parses the JSON response, and passes the.content field to a Function-constructor evaluator (`new (Function.contructor)(...)`) for execution. The paste-style host is anonymous and the fetched content is fully mutable — any consumer that imports this package executes whatever JavaScript the operator of that paste serves at that moment, with no signature, hash, or pinning. The package metadata advertises 'MongoDB connection driver' but the shipped index.js is a verbatim copy of Node's built-in `path` module with the dropper appended; the name 'mddriver' and the misleading description are consistent with a typosquat targeting developers searching for mongodb / mongoose drivers.\n\nAny computer that has this package installed or running should be considered fully compromised.
