AI Analysis
Technical Summary
TencentCloudBase CloudBase-MCP up to version 2.17.0 contains an SSRF vulnerability in the openUrl function located in mcp/src/interactive-server.ts within the open-url API endpoint. By manipulating the req.body.url parameter, an attacker can cause the server to make arbitrary HTTP requests. This vulnerability is remotely exploitable without requiring privileges or user interaction. The issue is fixed in version 2.17.1, with the patch identified by commit 3f678a1e7bd400cd76469d61024097d4920dc6b5.
Potential Impact
Successful exploitation allows an unauthenticated remote attacker to induce the server to send crafted HTTP requests to arbitrary URLs. This can lead to unauthorized internal network scanning, information disclosure, or interaction with internal services that are otherwise inaccessible. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, no privileges required, and low to limited impact on confidentiality, integrity, and availability.
