A second file lib/telemetry.js labelled as a telemetry SDK contains the same write+chmod+spawn primitives (Buffer.from(chunks,'base64'), cp.spawn('/bin/sh',['-c', filePath+' &']), fs['chmod'+'Sync'](extensionPath, 0755)) as a redundant dropper. The behavior fires whenever any consumer require()s the package, giving arbitrary remote code execution on the installer's host.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-data-schema-generator"},"versions":["35.2.1"],"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":"_bootstrap.js","sha256":"d0fd1f509dd1c86975d12ed0a7fae9dc708927be2dc5c3cfc15e1c7ad7f421be","tlsh":"15b1979a12a671084bb0e7e4c7178815f66bf663368182d8f7ac65844f73124c3b2efc"},{"path":"lib/telemetry.js","sha256":"ea4233422f41d791456b450335d404a15ea2f67195da50fa8549f85912baf996","tlsh":"23835056566a142186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-data-schema-generator-35.2.1.tgz","hashes":{"sha1":"312447a1d4d5c3da8fcfd24f3e8313ba1755065e","sha512_sri":"sha512-T5wFdVYXRnb91Jz0NBROYrbQnDbPU1fnvlNLGV+eYutEJkXlpq/xd1lVUYdrh412E5nqiNbk8a/Ua/3ANPsoeQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-data-schema-generator/v/35.2.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015469","import_time":"2026-08-05T15:19:53.124985795Z","modified_time":"2026-08-05T14:51:23Z","sha256":"b1e39c2d94a6114333c4275444d786188f00056a96e6e6296cd3abf275e3d5bc","source":"amazon-inspector","versions":["35.2.1"]}]}}
