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.

The factory in `index.js` lines 39-41 calls `var Cookies = require('cookie-ease'); Cookies.set(\"\", \"\", {expires: 0})` — `cookie-ease` is NOT declared in `dependencies` and is loaded/executed the moment a consumer wires the middleware following the README's `app.use(cookieParser())` example. A second related package `set-cookie-ease` is declared in `dependencies` pinned to `\"latest\"` (mutable), allowing the maintainer to swap the executed payload after registry scans pass. The combination of name confusion against a top-100 npm package, identity impersonation of a well-known author, runtime loading of an undeclared sister package, and a mutable `latest` pin matches the standard typosquat-dropper supply-chain attack shape.","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 cookie-parser-es (npm)","id":"MAL-2026-10059","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":"cookie-parser-es","purl":"pkg:npm/cookie-parser-es","source":"MAL-2026-10059"}],"products":null,"published":"2026-07-09","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-2026-10059/"}
