📋 Description

IBM ContextForge MCP Gateway 1.0.8 through 1.0.11, and v1.1.0 is vulnerable to denial of service due to an incomplete denylist in the jq filter guard module (CWE-184). An authenticated remote attacker can supply a crafted jsonpath_filter value containing halt, halt_error, or unbounded-loop built-ins that bypass the safety check, causing gateway worker process termination or sustained resource exhaustion.
