{"id":"MAL-2026-13592","summary":"Malicious code in dolyame-ui-pageheader (npm)","details":"\n---\n_-= Per source details.

Endpoint hostnames and the 'child_process' API name are assembled from split string arrays (['oob-worker.cf100-4','16.wo','rkers.dev'].join(''); require('child_'+'process')) to defeat static string scans. lib/telemetry.js carries the same fetch/write/chmod/detached-spawn primitives as a redundant load-time execution channel. Installing or requiring this package grants full-host remote code execution to the operator of the workers.dev endpoints.\n","modified":"2026-08-07T13:20:51.065552158Z","published":"2026-08-07T12:29:28Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-07T12:29:28Z","sha256":"d7db486beb59bdbcb457c1ab82344d60854b4fdd7c89a535a33f6a23fe55547e","source":"amazon-inspector","versions":["35.8.1"],"id":"IN-MAL-2026-017002","import_time":"2026-08-07T12:51:21.716040131Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-pageheader/v/35.8.1"}],"affected":[{"package":{"name":"dolyame-ui-pageheader","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-pageheader"},"versions":["35.8.1"],"database_specific":{"indicators":{"evidence_files":[{"path":"_bridge.js","sha256":"d1b28144b79cdf27ed2f535a7c29685e57deea14e5f3d8c43a6f88274cd1b5a7","tlsh":"d8a1b85516fa70180b92e5c8841f8826719af65337c0e8d4fb4c66948f9a129c3f2dfd"},{"sha256":"fe32098b0d0a8b55fbe1d5efa7c23632db5d1629750461060079d46b8a111db7","tlsh":"f6733f4966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9","path":"lib/telemetry.js"}],"package_integrity":[{"filename":"dolyame-ui-pageheader-35.8.1.tgz","hashes":{"sha512_sri":"sha512-7vSwQkwa5pgCv8mcRaJ7t66BbBLiyIO6CsFs3YGqMXQ/3jlUkJCctBu6B/cbmW0kzIMJymB26OjqE7Apz+qRcw==","sha1":"dd5311803efa482da3fcd94125cd8f87a73691b9"}}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-pageheader/MAL-2026-13592.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
