CVE-2026-71216— Apache SkyWalking: PagerDuty alarm hook transmits the integration routing key over cleartext HTTP

Quick assessment

Affected
Apache Software Foundation Apache SkyWalking
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以下是该漏洞描述的中文翻译： PagerDuty 报警钩子（alarm hook）通过明文 HTTP 传输集成路由密钥（routing key）。 PagerDuty 通常通过 HTTPS 提供该端点，并会对纯 HTTP 请求返回重定向响应。但这并未消除信息泄露的风险。包含路由密钥的 JSON 请求体所在的初始 POST 请求，在任何重定向响应被接收之前，就已以未加密的形式写入套接字（socket）。重定向仅影响后续请求是否通过安全通道重试，并不改变初始请求已经以明文形式离开主机这一事实。 此问题影响 Apache

Vulnerability Title
Apache SkyWalking: PagerDuty alarm hook transmits the integration routing key over cleartext HTTP
Source: CVE Program / CVE List V5
Vulnerability Description
PagerDuty alarm hook transmits the integration routing key over cleartext HTTP. PagerDuty serves this endpoint over HTTPS and will normally answer plain HTTP with a redirect. That does not remove the exposure. The initial POST -- including the JSON body containing the routing key -- is written to the socket unencrypted before any redirect response is received. Redirection affects only whether the request is retried securely, not whether the first copy left the host in the clear. This issue affects Apache SkyWalking: from 9.6.0 through 11.0.0. Users are recommended to upgrade to version 11.0.0, which fixes the issue.
