Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Daily Prayer Time < 2021.08.10 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Daily Prayer Time the fix is 2021.08.10: builds < 2021.08.10 are affected, anything from 2021.08.10 onward is not.

Remediation

Update to version 2021.08.10, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Daily Prayer Time: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Daily Prayer Time 2021.08.10 closes this, and updating the plugin is the step that ends it.
