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-2026-6661/ (Markdown: https://insights.sbomify.com/MAL-2026-6661/index.md)","id":"MAL-2026-6661","markdown":"https://insights.sbomify.com/MAL-2026-6661/index.md","name":"MAL-2026-6661","record":{"aliases":["GHSA-jpg2-3r22-63v7"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package ships a verbatim copy of the Express 'cookie-parser' middleware under a different name ('clx-cookieparser') and declares a repository field 'expressjs/clx-cookieparser' that does not exist under the expressjs GitHub organization, suggesting unauthorized association with the upstream project. The shipped code (index.js requires 'cookie' and 'cookie-signature' and re-implements cookie-parser) contains no network I/O, no install/lifecycle scripts, no obfuscation, and no credential handling — there is no demonstrated installer-side harm. The concern is name/metadata confusion: a developer searching for or mistyping 'cookie-parser' could install this lookalike, and the false repository attribution amplifies the confusion. Routing to human review so a maintainer can assess intent (benign mirror vs. squat positioning) and registry action.\n\nAny computer that has this package installed or running should be considered fully compromised.
