Several attributes are characteristic of dependency-confusion staging: a 99.99.99 version (well above any plausible real release), an 'internal testing' description, and a scope (@doaction) that may shadow an internal namespace. The actual install-time impact depends entirely on @doaction/shared's implementation of `collectEnv` and the preinstall script, which cannot be confirmed from this tarball alone. Routing for human review to confirm whether @doaction/shared is attacker-controlled (dependency-confusion attack) and to assess the env-collection behavior it actually performs at install time.\n\n## Source: ghsa-malware (2cfab693f8195c9b7d400aa6bcc6db510b89cd4920bdb622cc06b369a4ed226f)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n","affected":[{"package":{"ecosystem":"npm","name":"@doaction/eventemitter"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["9.9.9","99.99.99"],"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"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"domains":["e1gjv2ne5a.execute-api.ap-northeast-1.amazonaws.com"],"evidence_files":[{"path":"scripts/preinstall.js","sha256":"0b25bcd00b225a3623f30b69b974d451557e06dc9cd2a037c028fbfe9b139f02","tlsh":"4ce0237831e8b03c7cb919b52207034133a5901805387984b8ce07228aaf080663b983"}]}}}],"references":[{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-926j-qqmq-889c"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@doaction/eventemitter/v/9.9.9"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@doaction/eventemitter/v/99.99.99"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"source":"ghsa-malware","sha256":"2cfab693f8195c9b7d400aa6bcc6db510b89cd4920bdb622cc06b369a4ed226f","import_time":"2026-06-09T15:22:39.844003335Z","id":"GHSA-926j-qqmq-889c","modified_time":"2026-06-09T14:17:42Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}]},{"source":"amazon-inspector","sha256":"356613a140f3268f2633d292a37370ac2324af412bd3dbf6be2603f426db80cf","import_time":"2026-06-09T20:45:51.283247078Z","id":"IN-MAL-2026-005193","modified_time":"2026-06-09T20:19:14Z","versions":["9.9.9"]},{"source":"amazon-inspector","sha256":"5221b351f74900764906fd20a62e5c3f390473ed87a1d4fb781e34d3ffd2f623","import_time":"2026-06-09T20:45:51.049323193Z","id":"IN-MAL-2026-005192","modified_time":"2026-06-09T20:19:14Z","versions":["9.9.9"]},{"source":"amazon-inspector","sha256":"865100529f6c19b1eff05a47c96abd2d4eb5dba0d4fc0af838c307c816072a20","import_time":"2026-07-08T17:01:31.332557684Z","id":"IN-MAL-2026-008110","modified_time":"2026-07-08T16:26:19Z","versions":["99.99.99"]}]}}
