CVE-2022-1152
At a glance
CVE-2022-1152 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Menubar WordPress plugin, affecting versions <= 5.7.2. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). The issue is fixed in version 5.8; sites on affected versions should update now. Disclosed April 2022, reported by p7e4.
Vulnerability Overview
The Menubar WordPress plugin before 5.8 does not sanitise and escape the command parameter before outputting it back in the response via the menubar AJAX action (available to any authenticated users), leading to a Reflected Cross-Site Scripting vulnerability.
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 Menubar <= 5.7.2 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 Menubar the fix is 5.8: builds <= 5.7.2 are affected, anything from 5.8 onward is not.
Remediation
Update to version 5.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Menubar: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Menubar 5.8 closes this, and updating the plugin is the step that ends it.
