Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware
Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
hono: CORS Middleware reflects any Origin with credentials when `origin` defaults to the wildcard
Hono JWT Middleware's JWT Algorithm Confusion via Unsafe Default (HS256) Allows Token Forgery and Auth Bypass
Hono Improper Authorization vulnerability
DATABASE_URLTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
6/6 tools missing one or more hints — get_profile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_devices (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); query_health_data_type (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
4/6 tool handlers declare input schemas (67%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 2/6 tool handlers wrap calls in try/catch (33%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 6 high severity in production deps — @hono/node-server@1.13.8 (high), hono@4.7.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
