# CVE-2026-110194: IBM ContextForge MCP Gateway is affected by a server-side request forgery vulnerability

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

IBM ContextForge MCP Gateway 1.0.0 through 1.0.11 is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

## Remediation

- fix: 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: IBM strongly recommends upgrading to the fixed version.

If this is not possible restrict the accepted authorization server issuers by setting `DCR_ALLOWED_ISSUERS` to a list of trusted issuers, or disable Dynamic Client Registration (`DCR_ENABLED=false`), and restrict gateway creation permissions to trusted users. (source: CNA: ibm)
