CVE-2026-62253 · Severity: critical · CVSS 9.8 · Published 2026-10-07

Homer is a platform for managing SIP telephony infrastructure and VoIP call data. By default, if the JWT secret is not configured, all administrative API endpoints are completely unprotected, allowing any unauthenticated attacker to create admin accounts, read and modify user databases, and access stored call records.

## How to fix

- github.com/sipcapture/homer-app (Go): upgrade to 0.0.0-20260625093330-5e90809657c9 or later

  ```sh
  go get github.com/sipcapture/homer-app@v0.0.0-20260625093330-5e90809657c9
  ```


Set a strong, non-empty value for the JWT secret in the coordinator configuration before deployment. Do not rely on the default configuration in production environments.

## Technical details

The JWT middleware in both coordinator handlers contains a logic flaw where it bypasses authentication entirely when the JWT secret is an empty string, the default value. The middleware never validates tokens and passes all requests through unconditionally. This affects all protected endpoints under /api/v1, /api/v3, and /api/v4, allowing unauthenticated full administrative access including user creation, database enumeration, and configuration modification.
