嗯，用户让我总结一篇文章的内容，控制在一百个字以内，而且不需要特定的开头。我得先仔细阅读文章，抓住主要点。 文章讲的是一个安全漏洞，不是在常见的地方，而是在错误日志端点。测试人员注意到POST /tunnel/请求，看起来像是 telemetry 或日志记录，但深入分析发现可能有SSRF漏洞。 SSRF是什么？服务器根据用户控制的输入发起请求。这样攻击者可以让服务器访问内部服务或私有基础设施，可能引发严重问题。 所以总结的时候要包括：SSRF漏洞、隐藏在错误日志端点、通过用户控制输入影响服务器请求、潜在风险。 现在组织语言，确保简洁明了，不超过100字。 </think> 文章讲述了一个隐藏在错误日志端点中的SSRF（Server-Side Request Forgery）漏洞案例。测试人员通过分析看似无害的 telemetry 请求，发现服务器可能根据用户控制的输入发起 HTTP 请求，从而可能导致访问内部服务或私有基础设施的风险。 2026-2-19 04:44:41 Author: infosecwriteups.com(查看原文) 阅读量:3 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…
