CVE-2026-11918
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Summary
IBM ContextForge MCP Gateway <= v1.0.4 IBM mcp-context-forge could allow an authenticated user to bypass protection mechanisms due to incomplete recursive inspection of nested payload content.
Affected Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
| IBM | ContextForge MCP Gateway | <= v1.0.4 | affected |
Weaknesses
- CWE-184: CWE-184 Incomplete List of Disallowed Inputs
Workarounds
There is no workaround that fully prevents the bypass while keeping the affected plugins active. Operators may disable regex_filter and deny_filter in plugins/config.yaml to prevent exploitation, at the cost of losing the filtering controls those plugins provide.
IBM strongly recommends upgrading to v1.0.5 or higher, which replaces the top-level-only scan loops with a recursive walker in both plugins.
