Clerk JavaScript: SSRF in the opt-in clerkFrontendApiProxy feature may leak secret keys to unintended host

Clerk JavaScript is the official JavaScript repository for Clerk authentication. In @clerk/hono from versions 0.1.0 to before 0.1.5, @clerk/express from versions 2.0.0 to before 2.0.7, @clerk/backend from versions 3.0.0 to before 3.2.3, and @clerk/fastify from versions 3.1.0 to before 3.1.5, the clerkFrontendApiProxy function in @clerk/backend is vulnerable to Server-Side Request Forgery (SSRF). An unauthenticated attacker can craft a request path that causes the proxy to send the application's Clerk-Secret-Key to an attacker-controlled server. This issue has been patched in @clerk/hono version 0.1.5, @clerk/express version 2.0.7, @clerk/backend version 3.2.3, and @clerk/fastify version 3.1.5.

服务端请求伪造(SSRF)

Official Clerk JavaScript SDKs 代码问题漏洞

Official Clerk JavaScript SDKs是Clerk开源的一个用于 Clerk 身份验证的官方 Javascript 存储库。 Official Clerk JavaScript SDKs存在代码问题漏洞，该漏洞源于@clerk/backend中的clerkFrontendApiProxy函数存在服务端请求伪造，可能导致未经验证的攻击者通过特制请求路径将应用程序的Clerk-Secret-Key发送至攻击者控制的服务器。
