An attacker able to inject content into the renderer, such as by forging the /pc/upgrade/get API response using a publicly known AES key over an unvalidated TLS connection, can invoke os.navigateExternal with a file:// URL through an img onerror payload to execute arbitrary local binaries under the logged-in user's account.","published":"2026-10-12T20:17:08.840","modified":"2026-10-12T20:17:08.840","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://gist.github.com/LeoWSY-hashblue/10e5383fc2d4d75faf74a9507c6bba9f"},{"type":"WEB","url":"https://hr.163.com/product.html/music"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/netease-cloud-music-rce-via-os-navigateexternal-ipc"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-12T20:17:08.840"}}
