DescriptionHomer is open source telecom observability software. Prior to version 11.0.283, both JWT middleware functions (`JWTMiddleware` and `JWTMiddlewareV4`) immediately return `next(c)` when `jwtSecret == ""`. The JWT secret defaults to an empty string. On a default installation, all protected API endpoints under `/api/v1`, `/api/v3`, and `/api/v4` are completely unauthenticated. Version 11.0.283 patches the issue.
