The script reads the installer's OS username (from process.env USER/USERNAME) and hostname (os.hostname()), embeds them into a subdomain of a hardcoded 4otph6fase1x2won0hrfzul2wt2qqge5.oastify.com callback host, and transmits them via both a DNS lookup and an HTTPS GET to that host at path /depconf/. The behavior is consistent with a dependency-confusion probe using Burp Collaborator (oastify.com) infrastructure; installer identifiers (username, internal hostname, timestamp, package name) are disclosed to a third-party callback domain on every install.\n","affected":[{"package":{"ecosystem":"npm","name":"@wbnr/frontend-shared"},"versions":["99.0.0","99.0.1"],"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":"preinstall.js","sha256":"e54aed4cc27b61f78dd095fb67b92e1dff62bd9508b16f0b56d66357611dbb0d","tlsh":"fc0123f8b3e5eb310cd013c4b16c2e2f565be3a231ce9892085563c207b3a71c310ba8"}],"package_integrity":[{"filename":"frontend-shared-99.0.0.tgz","hashes":{"sha1":"110a186c4d8b59c46565976372a795ecc1157607","sha512_sri":"sha512-ILBG4IsmDmnQjWKchK65cChG/k4uM2p5wY/ytgcVYpzCAluOM9LALSBXa9T+PgprGkmlVKe3D8WGK12lmwXwTw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wbnr/frontend-shared/v/99.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wbnr/frontend-shared/v/99.0.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016680","import_time":"2026-08-06T18:09:05.150583525Z","modified_time":"2026-08-06T16:22:04Z","sha256":"6208a0da32b8b7ae795d85ecbf95788b876729db08b0a595ad24f05a02dbbdbe","source":"amazon-inspector","versions":["99.0.0"]},{"id":"IN-MAL-2026-016675","import_time":"2026-08-06T18:09:04.478112375Z","modified_time":"2026-08-06T16:19:30Z","sha256":"d10e6da61faa186ed684c79707395158b1fd639ebe55ab4b36f13d8f98789fa1","source":"amazon-inspector","versions":["99.0.1"]}]}}
