CVE-2026-5832 Details
Description
A weakness has been identified in atototo api-lab-mcp up to 0.2.1. This affects the function analyze_api_spec/generate_test_scenarios/test_http_endpoint of the file src/mcp/http-server.ts of the component HTTP Interface. This manipulation of the argument source/url causes server-side request forgery. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A server-side request forgery (SSRF) vulnerability has been identified in atototo api-lab-mcp versions through 0.2.1. The vulnerability exists in the HTTP interface, specifically within the tools 'analyze_api_spec', 'generate_test_scenarios', and 'test_http_endpoint'. The issue arises because the 'source' and 'url' arguments are not properly sanitized before being used in outbound HTTP requests. This flaw allows attackers to manipulate these arguments, causing the server to make unauthorized requests to internal services, cloud metadata endpoints, or other restricted locations. Such actions could lead to unauthorized information disclosure and further compromise.
No specific remediation is known at this time.
