The package name @medisend/core with version 0.0.1-security-research and a description referencing a dependency-confusion test targets internal builds that expect a private @medisend/core package; when such a build resolves this public package instead, the postinstall runs automatically and leaks the installer's hostname off-host. The self-labelled 'security research' framing does not change the effect: any installer that resolves this package executes an unconsented host-identifier beacon to a destination controlled by whoever provisioned the webhook.site URL.\n","affected":[{"package":{"ecosystem":"npm","name":"@medisend/core"},"versions":["0.0.1-security-research"],"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":"package.json","sha256":"a185b39ae0922db4364de88d75b9a1a1322cc478d5adc48f220916f180321b92","tlsh":"b2e072b53018203326e902aa0830900db932ca0a204a1f1fcac603a8a20c6f68712aca"}],"package_integrity":[{"filename":"core-0.0.1-security-research.tgz","hashes":{"sha1":"2f037d364f913355759d717e0cf38d68fc068f0b","sha512_sri":"sha512-AZQsoHKGzDV7qg/+l7GSlN0ecz90A5aulcPjRDaYISIqn/vVPkBv6HYWodSAvMvhSb5FjekN5xNPquDmq6Waxg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@medisend/core/v/0.0.1-security-research"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018652","import_time":"2026-08-24T16:49:15.09301005Z","modified_time":"2026-08-24T16:46:21Z","sha256":"18f32429d1bfdc9438f2f03f531e5c2fef53e0e69104e3124499cf6f42ce52a1","source":"amazon-inspector","versions":["0.0.1-security-research"]}]}}
