How does WordSec protect against this?

The attempt arrives as an ordinary request to YOP Poll: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: YOP Poll 7.0.6 closes this, and updating the plugin is the step that ends it.
