JWT Authentication Bypass in Homer

Publication date: 2026-10-07

Last updated on: 2026-10-07

Assigner: GitHub, Inc.

Description
Homer 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.

Executive Summary

CVE-2026-62253 is an authentication bypass vulnerability in Homer, an open-source telecom observability tool. When the JWT secret is empty (the default setting), the JWT middleware functions skip authentication checks, allowing unauthorized access to protected API endpoints under /api/v1, /api/v3, and /api/v4.

Detection Guidance

Check Homer's configuration file for an empty JWT secret setting. Verify if protected API endpoints under /api/v1, /api/v3, or /api/v4 allow unauthenticated access by sending requests without tokens. Inspect logs for unusual access patterns to these endpoints.

Impact Analysis

This vulnerability allows attackers to access sensitive data and perform unauthorized actions without credentials. They could read or modify user data, database connections, and VoIP call records. The impact is severe due to the high CVSS score of 9.8, indicating critical risk.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and access control, such as GDPR and HIPAA, by allowing unauthorized access to sensitive data. Organizations using affected Homer versions may face regulatory penalties and reputational damage.

Mitigation Strategies

Upgrade Homer to version 11.0.283 or later. If upgrading is not possible, explicitly set a non-empty JWT secret in the configuration and restart the service. Ensure the secret is persisted in .homer_jwt_secret for stability.
