IBM ContextForge MCP Gateway: path traversal
No fix yet
IBM ContextForge MCP Gateway 1.0.0 through 1.0.8 was vulnerable to path traversal in its Admin API log-download endpoint (GET /v1/admin/logs/file). The path confinement check uses str.startswith() rather than proper boundary validation, allowing an authenticated admin to read .log, .jsonl, and .json files outside the configured LOG_FOLDER by supplying a filename that resolves into a sibling directory whose absolute path shares the log directory's string prefix.
