# CVE-2026-110178: IBM ContextForge MCP Gateway is affected by an improper access control vulnerability in configuration import

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

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.

## Remediation

- 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 ] (source: CNA: ibm)
- workaround: 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. (source: CNA: ibm)
