{"id":"MAL-2026-10084","summary":"Malicious code in conversionvaluemanager (npm)","details":"\n---\n_-= Per source details.

The package.json description self-identifies as a dependency-confusion proof-of-concept (\"PoC - Dependency Confusion - Bug Bounty by ha4x0r\"), and the package name targets an internal/private package name. Any organization whose build misresolves to this public package leaks host, user, and environment identifiers to the third-party Collaborator endpoint on install. PoC/bug-bounty framing does not change the installer-side impact: the beacon fires on every install.\n","aliases":["GHSA-c8w9-r7mv-28q4"],"modified":"2026-09-01T11:31:32.273893167Z","published":"2026-07-09T17:00:59Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-07-09T17:19:28.960426558Z","modified_time":"2026-07-09T17:00:59Z","sha256":"21445a74cc1c4d33c89f1a7d8c357c79d5adb11cda135c813676b23c875418e9","source":"amazon-inspector","versions":["3.0.0"],"id":"IN-MAL-2026-009360"},{"versions":["3.0.0"],"id":"RLMA-2026-05522","import_time":"2026-07-20T13:14:45.210269957Z","modified_time":"2026-07-20T10:38:10Z","sha256":"8a0866f3469405ec2768c987abf110354927c943f2d2a5303834ff7e6deccf5f","source":"reversing-labs"},{"sha256":"24dbc577c559551551b0c3789a0372f81b9f34699527ff29265da7912ff49c70","source":"reversing-labs","id":"RLUA-2026-06165","import_time":"2026-09-01T11:18:01.09108056Z","modified_time":"2026-08-24T16:45:27Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/conversionvaluemanager/v/3.0.0"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-c8w9-r7mv-28q4"}],"affected":[{"package":{"name":"conversionvaluemanager","ecosystem":"npm","purl":"pkg:npm/conversionvaluemanager"},"versions":["3.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/conversionvaluemanager/MAL-2026-10084.json","cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"evidence_files":[{"tlsh":"e7f0acf0a2a5ebb81974a7d0a26a080793bbd1057d5bbcd1daa940986b5c2a402b05f4","path":"postinstall.js","sha256":"dadaad150a1789aec709a78a41507ff0d88d2ab999dc6622e3574d9ea5f34b49"},{"path":"package.json","sha256":"5c3b9e3047d939f4160b1a93994530150054fdc54004292ba8fa3e5287d5d6a2","tlsh":"dfd097240e62aa3378c50b860833500f27324e0b020c7c8c13e724a8229e3b74abf31f"}],"package_integrity":[{"filename":"conversionvaluemanager-3.0.0.tgz","hashes":{"sha512_sri":"sha512-v5eYv9MQ27vNNjFWjRJoadgOlE9Y9EPY7QVPzwaJ+5HfF9wovie2dWlmDCivObNOS0kDYFiiPSb4fsoayPz0JA==","sha1":"dd96a7ab22110ff8458ff5a10bfcca9e6eaead42"}}]}}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"ReversingLabs","contact":["https://www.reversinglabs.com"],"type":"FINDER"}]}
