Technical Analysis

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

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

Reaching this weakness in Vertical scroll recent post < 14.0 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 Vertical scroll recent post the fix is 14.0: builds < 14.0 are affected, anything from 14.0 onward is not.

Remediation

Update to version 14.0, or a newer patched version

The attempt arrives as an ordinary request to Vertical scroll recent post: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Vertical scroll recent post 14.0 closes this, and updating the plugin is the step that ends it.
