CVE-2026-110178
IBM ContextForge MCP Gateway is affected by an improper access control vulnerability in configuration import
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.
Fixes and workarounds
Fix
IBM strongly recommends addressing the vulnerability now. Product(s)Version(s) number and/or range Remediation/Fix/InstructionsIBM ContextForge MCP Gatewayv1.1.0Install or upgrade to v1.1.0 [ v1.1.0 Release Notes https://github.com/IBM/mcp-context-forge/releases/tag/v1.1.0 ]

None. IBM strongly recommends upgrading to the fixed version. Until upgrading, administrators can reduce exposure by not granting `admin.import` to team-scoped roles and by reserving configuration import for platform administrators.
