CVE-2026-25116 – Runtipi vulnerable to unauthenticated docker-compose.yml Overwrite via Path Traversal

CVE ID : CVE-2026-25116

Description : Runtipi is a personal homeserver orchestrator. Starting in version 4.5.0 and prior to version 4.7.2, an unauthenticated Path Traversal vulnerability in the `UserConfigController` allows any remote user to overwrite the system’s `docker-compose.yml` configuration file. By exploiting insecure URN parsing, an attacker can replace the primary stack configuration with a malicious one, resulting in full Remote Code Execution (RCE) and host filesystem compromise the next time the instance is restarted by the operator. Version 4.7.2 fixes the vulnerability.

Severity: 7.6 | HIGH
