What is CVE-2026-109424?
CVE-2026-109424 is a high-severity vulnerability in NetEase Cloud Music for Windows, published on 12 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a weak encryption vulnerability where /eapi/ and /xeapi/ API response bodies are decrypted using a fixed, publicly documented AES-128-ECB key with no integrity credential. 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.
