The `buildoptimize` function issues an HTTP request to the hardcoded URL https://vercel-node-rouge-beta.vercel.app/icons/23 and passes the response body to `eval(JSON.parse(b))` with no integrity check. Any caller that invokes `buildoptimize()` runs whatever JavaScript the attacker-controlled Vercel preview endpoint returns at that moment, granting remote code execution on the installer's machine. The advertised ErrorBoundary API does not exist, confirming the package is a lure rather than a misnamed legitimate library.\n","affected":[{"package":{"ecosystem":"npm","name":"react-error-lint"},"versions":["1.1.6"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"206b5d672da63143ded7ee4f0081782900866accb8c43bd4e07988cd09b85329","tlsh":"a85156a21d8021235573efe46707c524f775e236729182b2b99f85d01fb7694a693ccc"},{"path":"README.md","sha256":"3bf38f34f29547b25227f7d043d64c5ba8721d23875c6874ccc2b89933d12ede","tlsh":"88f1a8a7e5c271770c73116691663a09db6f623d063a10a1715f83ab3fa0469cf1fadc"}],"package_integrity":[{"filename":"react-error-lint-1.1.6.tgz","hashes":{"sha1":"2cdc932e39dff8a2081b6ee1990fb5ffa08c129b","sha512_sri":"sha512-vB2Ur27skmvJJ+slgW2prO0NNoLiM2M/lvegxci7HrKLZfC1oXNsYis7+MSbB6r1U0lOJwk8eb0Hmoq3gIoYAA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/react-error-lint/v/1.1.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-007012","import_time":"2026-06-18T17:08:48.285695068Z","modified_time":"2026-06-18T16:32:46Z","sha256":"a084c9e71eac856bf1a1fec025773cc561f9f6677c187d60e055b89c73d846b9","source":"amazon-inspector","versions":["1.1.6"]}]}}
