A freshness marker is written to /tmp/.analytics_state. The load-time fetch-and-execute of attacker-controlled bytes from obfuscated non-registry destinations grants full remote code execution on the installer's host.\n","modified":"2026-08-05T15:52:42.010180508Z","published":"2026-08-05T15:18:48Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-05T15:18:48Z","sha256":"7679dd0e86411f0df5eea8392ad6f6a663ab0d911cd674b3ef4605af846cb323","source":"amazon-inspector","versions":["35.6.5"],"id":"IN-MAL-2026-015649","import_time":"2026-08-05T15:20:01.618729236Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-breadcrumbs/v/35.6.5"}],"affected":[{"package":{"name":"dolyame-ui-breadcrumbs","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-breadcrumbs"},"versions":["35.6.5"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"evidence_files":[{"path":"_bridge.js","sha256":"6a81148ec7c2a3a54aeae0fb9830f0e6f4c093e78608c7c765c566fe2bfb979e","tlsh":"3bb1866a15a670188bb0d7e0c6175416fa5af66333809684fb9ca5881fb352483b2efc"}],"package_integrity":[{"filename":"dolyame-ui-breadcrumbs-35.6.5.tgz","hashes":{"sha512_sri":"sha512-ya5dn7SXLR+r0hKbMuZmq2XueKbxudmdi6L76x0BEivgtdy1vAXgTk4LPpVZ+wwKogJvwL0PvT21vVpNslO83Q==","sha1":"c668a6cca6e03e0780715d7962c501d7c180bc63"}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-breadcrumbs/MAL-2026-13138.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
