At a glance
CVE-2022-1644 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Call&Book Mobile Bar WordPress plugin, affecting versions <= 1.2.2. It carries a CVSS score of 4.8 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Admin level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed May 2022, reported by Vinay Varma Mudunuri.
Vulnerability Overview
The Call&Book Mobile Bar WordPress plugin through 1.2.2 does not sanitize and escape some of its settings, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed.
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 Call&Book Mobile Bar <= 1.2.2 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. No fixed build of this plugin is recorded for Call&Book Mobile Bar yet, so installs running <= 1.2.2 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
