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.

Its sole exported function `middleware` (index.js:117-122) detached-spawns `node lib/logger.js` with `{ detached: true, stdio: 'ignore' }` and immediately `unref()`s the child, so the loader runs silently and outlives the parent process. lib/logger.js then uses axios to GET `https://www.jsonkeeper.com/b/YL7GN`, extracts the JS payload from the response's `Cookie` field, and evaluates it with `new Function.constructor('require', s)(require)`, retrying up to 5 times. This grants attacker-controlled JavaScript full `require` access in the consumer process. The remote URL is disguised in lib/logger.js:4-8 as `DEV_API_KEY` inside a fake `process.env`-shaped object to look like benign configuration. jsonkeeper.com is an anonymous, author-mutable paste host, so the executed bytes can change at any time without any package update. Any application that imports this package and invokes the default `middleware` export will execute remote attacker code.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in requests-middleware (npm)","id":"MAL-2026-6096","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"requests-middleware","purl":"pkg:npm/requests-middleware","source":"MAL-2026-6096"}],"products":null,"published":"2026-06-18","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-6096/"}
