Any environment that imports or requires this package leaks its browser cookies to an anonymous third-party listener controlled by the package author. The destination is a webhook.site inbox — an anonymous request-capture service unrelated to any legitimate feed-widget functionality — and the transmission fires unconditionally on load, with no caller opt-in or configuration.\n","modified":"2026-09-21T04:00:07.698294714Z","published":"2026-09-21T03:30:57Z","database_specific":{"malicious-packages-origins":[{"versions":["1.0.0"],"id":"IN-MAL-2026-020231","import_time":"2026-09-21T03:46:38.157628355Z","modified_time":"2026-09-21T03:30:57Z","sha256":"b5a81a96715497c25b18687ba7b9b42e919c23e700ede8d9944d41d6052d7f83","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/feed-widget-helper/v/1.0.0"}],"affected":[{"package":{"name":"feed-widget-helper","ecosystem":"npm","purl":"pkg:npm/feed-widget-helper"},"versions":["1.0.0"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"package_integrity":[{"hashes":{"sha1":"ff36ee16ab0f4bac3574f146ecfa81e8393f74b8","sha512_sri":"sha512-HDWGxlNa+Sf+lohD34tWUwuYzLw4mT2GLNejZhIyv2bNYxCTykSgM/GVK9r+3FnjJjhi/bgRx3bSjzF1+UU75Q=="},"filename":"feed-widget-helper-1.0.0.tgz"}],"evidence_files":[{"tlsh":"cbb012ffa204883d18f8c4447321998cd698b1209c556906dcfd65f0a33220f3d00fb2","path":"index.js","sha256":"1b985d71a7f326e55b032a7fa220472987bd770cfbfb2e907a19127887e1165e"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/feed-widget-helper/MAL-2026-16332.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
