Remediation

Update to version 2.8.10, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Post Form 2.8.10 closes this, and updating the plugin is the step that ends it.
