CVE-2022-2325
At a glance
CVE-2022-2325 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Invitation Based Registrations WordPress plugin, affecting versions <= 2.2.84. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 2.3.1; sites on affected versions should update now. Disclosed July 2022.
Vulnerability Overview
The Invitation Based Registrations WordPress plugin through 2.2.84 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)
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 Invitation Based Registrations <= 2.2.84 takes an account at Admin level or above. 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 Invitation Based Registrations the fix is 2.3.1: builds <= 2.2.84 are affected, anything from 2.3.1 onward is not.
Remediation
Update to version 2.3.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Invitation Based Registrations 2.3.1 closes this, and updating the plugin is the step that ends it.
