Attackers who can intercept or originate server responses can construct valid ciphertext under the known key with PKCS#7 padding, enabling the client to accept forged API responses that serve as a prerequisite for further exploitation such as reaching the os.navigateExternal bridge.","categories":["Unclassified"],"product":"NetEase Cloud Music for Windows","vendor":"NetEase","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109424","source_modified_at":"2026-10-13T17:19:55.260Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"NetEase Cloud Music for Windows","vendor":"NetEase","versions":[{"status":"affected","version":"3.1.38","versionType":"custom"},{"status":"affected","version":"3.1.39.205426","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00156,"percentile":0.0441,"score_date":"2026-10-23"},"published_at":"2026-10-12T19:35:20.198Z","modified_at":"2026-10-13T17:19:55.260Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109424","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T17:19:55.260Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109424","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://gist.github.com/LeoWSY-hashblue/10e5383fc2d4d75faf74a9507c6bba9f","tags":["technical-description"]},{"source":"CVE List","url":"https://hr.163.com/product.html/music","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/netease-cloud-music-weak-encryption-via-eapi-xeapi","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T17:19:10.711877Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T17:19:55.260Z","content_hash":"0e2a6a2510a40e38c45071885574756fb9d0ae8004a99dfe90f327c4fd107900"}}
