When the module is required/imported in any browser-like environment (browser bundling, jsdom, Electron renderer), this causes arbitrary JavaScript from the unrelated `px8my` npm package — at whatever version its owner most recently published — to execute in the host page context. The destination is a different publisher's package, the version is unpinned (so the executed bytes are author-mutable at any time by a third party), and there is no documented purpose for this loader behavior. Package metadata reinforces the loader/lure shape: empty author, empty description, no repository, default test script — a throwaway package whose only function is to pull in remote third-party code. An installer that bundles or loads pxpure8 ends up shipping whatever px8my publishes, including any future malicious version, into their own application's execution context.\n","affected":[{"package":{"ecosystem":"npm","name":"pxpure8"},"versions":["1.0.2"],"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":"pure.js","sha256":"86002d8a49e829ca7d529eb48e10f7f27c46269556ba67667fd1314a40e4fc9c","tlsh":"e1c0806a651575344255509d3037d6b478f3112965119181456ddc190d61d811c5fc90"},{"path":"package.json","sha256":"4281502bbb94b3de31549000e2a3b17652df7c1dcaacb3232a2ced75384aa5eb","tlsh":"e4d0a7141961953315c455260e399153b721df5f00547c0d57cf282c52cfa736cfa30d"}],"package_integrity":[{"filename":"pxpure8-1.0.2.tgz","hashes":{"sha1":"5586296c2a656fb3fecefc2b98dce1dc0dde7d2e","sha512_sri":"sha512-zl6TenA1lLpGO7wunk6KDGbob6qNgimLoIVewUIlR3hzBjndpQMNxDnGgYH6IcpXQqqJX5yy4LERiTYtk3oeTA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/pxpure8/v/1.0.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-009600","import_time":"2026-07-09T23:30:56.316754416Z","modified_time":"2026-07-09T23:09:27Z","sha256":"a40ae433e9fa90bfbb449d343c281375329a44c0dacf080a91a0c1717579b679","source":"amazon-inspector","versions":["1.0.2"]}]}}
