| Title | hekmon8 Jenkins-server-mcp 0.1.0 Server-Side Request Forgery |
|---|
| Description | A Server-Side Request Forgery (SSRF) vulnerability was identified in Jenkins-server-mcp 0.1.0. The issue exists in multiple MCP tools within src/index.ts, such as get_build_status and get_build_log, which accept a user-controlled jobPath argument. This argument is concatenated into an Axios request URL without sufficient validation (e.g., /${args.jobPath}/...). By supplying a jobPath that starts with a leading slash (e.g., /127.0.0.1:7777/), an attacker can force the application to treat the URL as protocol-relative, effectively hijacking the request destination. This allows an attacker to bypass the intended JENKINS_URL configuration to probe internal network services, access cloud metadata endpoints, or interact with other private infrastructure resources. |
