好的，用户希望我用中文帮他总结一篇文章的内容，控制在100个字以内，而且不需要特定的开头。首先，我需要理解文章的主要内容。文章讲的是一个安全漏洞的故事，涉及到错误日志记录端点和SSRF攻击。 用户可能是一位开发人员或者安全测试人员，想快速了解文章的核心内容。他可能需要这个总结用于报告、学习或者分享。深层需求可能是希望掌握如何识别和防范类似的漏洞。 接下来，我要提炼关键点：测试人员发现了一个看似无害的端点/tunnel/，通过分析发现可以利用SSRF漏洞，进而控制服务器发送请求，访问内部服务和私有基础设施。总结时要简洁明了，涵盖这些要点。 最后，确保语言流畅自然，不超过100个字，并且直接描述内容。 </think> 测试人员发现目标网站的错误日志记录端点存在SSRF漏洞。通过分析发现，服务器会根据用户控制的输入发送请求。攻击者可利用此漏洞让服务器发送恶意请求，访问内部服务和私有基础设施。 2026-2-19 04:44:41 Author: infosecwriteups.com(查看原文) 阅读量:5 收藏

Hello readers,
Sometimes the most interesting vulnerabilities are not hiding in login forms, password reset flows, or API endpoints — they hide in the background. This story started with a feature that most testers completely ignore: an error logging endpoint.
While testing target.com, I noticed a request being sent to an endpoint called:
POST /tunnel/At first glance, it looked harmless. Just telemetry. Just logging. Just Sentry doing its thing. But security testing has taught me one important rule:
If the server makes a request based on something I control — I look closer. And that’s exactly what happened here.
Before We Dive In — What Is SSRF?
Server-Side Request Forgery (SSRF) happens when an application allows user-controlled input to influence a server-side HTTP request.
In simple terms:
Instead of sending requests directly to a system, I trick the server into sending them on my behalf.
Why does that matter?
Because servers can access internal services, reach private infrastructure, are…
