Any consumer that does `require('tw-theme-kit')` or `import 'tw-theme-kit/runtime'` triggers attacker-controlled code at load time with full Node capabilities (fs, child_process, net) exposed via the globals. This behavior is unrelated to the package's stated purpose (a Tailwind theme plugin) and matches the fingerprint of the 'Orion' obfuscated-loader campaign. The.mjs builds and source-maps embed the same obfuscated literal, so no entrypoint is safe.\n\n## Source: ghsa-malware (de70cc0bc70c11c34e04c2cdaea11b8e0173befc31c43e2921933c180736ffa3)\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.\n","affected":[{"package":{"name":"tw-theme-kit","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.1.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"dist/index.cjs","sha256":"ce9e98ae597db38c523eb0141be40b29d462e22edffad6be38b562193ff278e6","tlsh":"cc421985b7fa2623007394ed412b8016faa9b1421419f748f9ddd3e80f8a21ec9f57e9"},{"path":"dist/runtime.cjs","sha256":"eea38ba44c83cf0fc821802e00dec564f35ba062ce3817517b7c4af41bc4510f","tlsh":"83e13cc43bf97766217200a5121790067594b1838429f58cedeee3e90fda21f89f8bf9"}],"package_integrity":[{"filename":"tw-theme-kit-1.1.0.tgz","hashes":{"sha1":"190b3a8c76e72928ba27eaeec223ee1dc79563f5","sha512_sri":"sha512-wW+MgsdKOTDDfF3ldqEOFH84JJ4fxSXw6bjS6NXhtMTeXkIzuoGsXXKj2vvF58HTQCTQTxQASrYNLF08svZ0+A=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/tw-theme-kit/v/1.1.0"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-g2wq-vjqj-xc3h"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-006848","import_time":"2026-06-16T23:03:43.703368387Z","modified_time":"2026-06-16T22:21:38Z","sha256":"0144b9ea6743e481e49885f6375a8aa990e9a20bfc5da1148b7df59a9370736c","source":"amazon-inspector","versions":["1.1.0"]},{"id":"GHSA-g2wq-vjqj-xc3h","import_time":"2026-08-25T17:25:28.256918326Z","modified_time":"2026-08-25T16:29:19Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"de70cc0bc70c11c34e04c2cdaea11b8e0173befc31c43e2921933c180736ffa3","source":"ghsa-malware"}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
