Vulnerability Title
OAuth library for nim allows insecure generation of state values by generateState - entropy too low and uses regular PRNG instead of CSPRNG
Vulnerability Description
In the OAuth library for nim prior to version 0.11, the `state` values generated by the `generateState` function do not have sufficient entropy. These can be successfully guessed by an attacker allowing them to perform a CSRF vs a user, associating the user's session with the attacker's protected resources. While `state` isn't exactly a cryptographic value, it should be generated in a cryptographically secure way. `generateState` should be using a CSPRNG. Version 0.11 modifies the `generateState` function to generate `state` values of at least 128 bits of entropy while using a CSPRNG.

Vulnerability Title
oauth 安全漏洞
Vulnerability Description
oauth是Yoshihiro Tanaka个人开发者的一个适用于 nim 的 oauth 库。 oauth 0.11之前版本存在安全漏洞，该漏洞源于generateState函数生成的state值没有足够的熵，攻击者可以成功猜出这些值，从而对用户执行跨站请求伪造攻击，将用户的会话与攻击者的受保护资源相关联。
