CVE-2026-110189 IBM ContextForge MCP Gateway is affected by a denial of service due to an incomplete list of disallowed jq inputs

6.5 medium

Medium (6.5) in ibm contextforge mcp gateway.

On this page
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.

If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-110189 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.
