At a glance
This record tracks a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Codup Read Only Admin WordPress plugin, affecting versions <= 1.1.1.7. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). The issue is fixed in version 1.1.1.8; sites on affected versions should update now. Disclosed May 2022.
Vulnerability Overview
The plugin Codup Read Only Admin for WordPress is vulnerable to Cross-Site Scripting via the read_only_admin parameter in the save_user_meta function in versions up to and including 1.1.1.7 due to insufficient sanitization. This makes it possible to attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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 Codup Read Only Admin <= 1.1.1.7 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 Codup Read Only Admin the fix is 1.1.1.8: builds <= 1.1.1.7 are affected, anything from 1.1.1.8 onward is not.
Remediation
Update to version 1.1.1.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Codup Read Only Admin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Codup Read Only Admin 1.1.1.8 closes this, and updating the plugin is the step that ends it.
