# CVE-2026-62252

> 9.8 CRITICAL · 🧪 PoC

## Beschreibung

Homer is open source telecom observability software. Prior to version 11.0.283, on every fresh Homer deployment using internal authentication, the bootstrap process automatically creates an `admin` account with the password `sipcapture` (stored as a legacy SHA-256 hex hash). There is no first-login forced-change mechanism. Any attacker who reaches the login endpoint immediately gains full administrative access. Version 11.0.283 patches the issue.
