CVE-2026-110178: Access Control Flaw (CVSS 4.1)

Description

IBM ContextForge MCP Gateway 1.0.0 through 1.0.11 is vulnerable to improper access control in the bulk import path. A remote authenticated attacker holding a team-scoped `admin.import` permission can overwrite the endpoint URL, request headers, and authentication credentials of public tools, resources, and prompts owned by other tenants by sending a crafted POST request to `/v1/import` with `conflict_strategy=update`, redirecting subsequent AI gateway invocations to an attacker-controlled host.
