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.

On `require()`, the main entry performs a bare side-effect import of `layerd-unit-codec-parser/cjs-runner` (return value discarded) before any other work, and replaces the de-facto-standard `postcss-selector-parser` with `layerd-unit-codec-parser/selector-parser` (the standard parser is demoted to devDependencies). `layerd-unit-codec-parser` is an obscure package whose name has no relation to CSS or PostCSS; the `/cjs-runner` submodule path is shaped specifically to execute code on load. Installing this package silently pulls `layerd-unit-codec-parser` into the consumer's dependency tree and runs its `cjs-runner` module on every require of the wrapper.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","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 postcss-selector-minify (npm)","id":"MAL-2026-10614","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":["0"],"last_affected":[],"package":"postcss-selector-minify","purl":"pkg:npm/postcss-selector-minify","source":"MAL-2026-10614"}],"products":null,"published":"2026-07-14","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-2026-10614/"}
