When a consumer's build instantiates the plugin, it constructs a URL at runtime, calls fetch() against it, base64-decodes the response body, and executes the result via new Function(param, decoded)(require) inside a retry loop (up to 10 attempts, 60s timeout each). The obfuscation (130-entry RC4 string array with two indirection decoders and a self-defending console-hook stub) hides the network destination and the fetch/exec wiring; a legitimate PostCSS plugin for vendor prefixes and CSS variables has no reason to fetch and evaluate remote code. The eval runs with require in scope, giving the remote operator arbitrary code execution inside the consumer's build process.\n","affected":[{"package":{"ecosystem":"npm","name":"animate-css-vite"},"versions":["1.0.1"],"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":"plugin.js","sha256":"7c718f02be563d9673a30d8ed0d91e1b42773795043ab219fe0d21d0371a87d8","tlsh":"92321bbd3cf23614076b25e595ef08caa8b5a582384c7e44f16c85953f41f5ac1f396c"}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/animate-css-vite/v/1.0.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018326","import_time":"2026-08-19T03:49:30.46729361Z","modified_time":"2026-08-19T03:37:16Z","sha256":"67d6c86a03c6106e799d0817676fcc92f022b64790aab209aa9fe663c085c4e6","source":"amazon-inspector","versions":["1.0.1"]}]}}
