Unspecified vulnerability in the Youdao Dictionary (com.youdao.dict) application 1.6.1, 2.0.1(2), and 3.0.0(1) for Android has unknown impact and attack vectors.

HTTP Request Smuggling vulnerability in netease-youdao/qanything version 1.4.1 allows attackers to exploit inconsistencies in the interpretation of HTTP requests between a proxy and a server. This can lead to unauthorized access, bypassing security controls, session hijacking, data leakage, and potentially arbitrary code execution.

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.
