DOS Attack causes 100% CPU usage

[theAkito]

Describe the bug 100% CPU usage out of nothing, due to this app. After disabling it inside Nextcloud & force killing it on the OS, the CPU usage went down.

The high CPU usage was caused by an infinite spam of POST request onto the reverse proxy, which couldn't handle this DOS attack.

To Reproduce Unknown. I've just noticed the high CPU usage & have proven, without any doubt, that this app is responsible for it.

Expected behavior CPU usage should stay normal, i.e. no POST requests should be infinitely spammed onto the reverse proxy.
