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.

NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a TLS certificate validation vulnerability that allows a network-adjacent attacker to intercept and decrypt HTTPS traffic by failing to validate the server certificate chain, verify the hostname, or consult any Windows certificate trust store. Attackers can perform a man-in-the-middle attack using a rogue certificate authority to decrypt traffic, capture the MUSICU session credential sent in authenticated API requests, and modify server responses in transit, enabling account takeover and transport-layer response forgery.

NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a remote code execution vulnerability in the renderer-process IPC bridge os.navigateExternal, which passes caller-supplied URLs to ShellExecuteW without validating the URL scheme. 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.

An issue in NetEase (Hangzhou) Network Co., Ltd NeacSafe64 Driver before v1.0.0.8 allows attackers to escalate privileges via sending crafted IOCTL commands to the NeacSafe64.sys component.

A local file inclusion vulnerability exists in netease-youdao/qanything version v2.0.0. This vulnerability allows an attacker to read arbitrary files on the file system, which can lead to remote code execution by retrieving private SSH keys, reading private files, source code, and configuration files.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the backend API of netease-youdao/qanything, as of commit d9ab8bc. The backend server has overly permissive CORS headers, allowing all cross-origin calls. This vulnerability affects all backend endpoints, enabling actions such as creating, uploading, listing, deleting files, and managing knowledge bases.

A Denial of Service (DoS) vulnerability was discovered in the file upload feature of netease-youdao/qanything version v2.0.0. The vulnerability is due to improper handling of form-data with a large filename in the file upload request. An attacker can exploit this vulnerability by sending a large filename, causing the server to become overwhelmed and unavailable for legitimate users. This attack does not require authentication, making it highly scalable and increasing the risk of exploitation.

A stored Cross-Site Scripting (XSS) vulnerability exists in netease-youdao/QAnything. Attackers can upload malicious knowledge files to the knowledge base, which can trigger XSS attacks during user chats. This vulnerability affects all versions prior to the fix.

An Untrusted search path vulnerability in NetEase CloudMusic 2.10.4 for Windows allows local users to gain escalated privileges through the urlmon.dll file in the current working directory.

pomelo-monitor through 0.3.7 is vulnerable to Command Injection.It allows injection of arbitrary commands as part of 'pomelo-monitor' params.

Pomelo v2.2.5 allows external control of critical state data. A malicious user input can corrupt arbitrary methods and attributes in template/game-server/app/servers/connector/handler/entryHandler.js because certain internal attributes can be overwritten via a conflicting name. Hence, a malicious attacker can manipulate internal attributes by adding additional attributes to user input.
