IBM ContextForge MCP Gateway (mcp-contextforge-gateway) <= v1.0.6 MCP Context Forge could allow a remote authenticated attacker to obtain sensitive information due to a DNS rebinding vulnerability during tool invocation.
Workarounds/Mitigation guidance:
No complete workaround exists without upgrading. As a partial mitigation, restrict tool-creation
permissions (tools.create) to fully trusted users only, limiting the pool of accounts that could
stage a registration with a controlled hostname. This does not eliminate the vulnerability but
reduces exposure in environments where least-privilege access controls are enforced.
IBM strongly recommends upgrading to v1.0.7 or higher.
IBM strongly recommends addressing the vulnerability now.
