GHSA-9wqr-9787-p4rf: Bypass IP detection to brute-force password in Microweber

In the login API, an IP address will by default be blocked when the user tries to login incorrectly more than 5 times. However, a bypass to this mechanism is possible by abusing a X-Forwarded-For header to bypass IP detection and perform a password brute-force. A patch for this issue is available on the 1.2-dev branch of the Microweber GitHub repository.
