At a glance
CVE-2021-24752 is a medium-severity Missing Authorization vulnerability in the Catch Duplicate Switcher WordPress plugin, affecting versions < 1.6. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.6; sites on affected versions should update now. Disclosed September 2021, reported by apple502j.
Vulnerability Overview
Multiple Plugins from the CatchThemes vendor do not perform capability and CSRF checks in the ctp_switch AJAX action, which could allow any authenticated users, such as Subscriber to change the Essential Widgets WordPress plugin before 1.9, To Top WordPress plugin before 2.3, Header Enhancement WordPress plugin before 1.5, Generate Child Theme WordPress plugin before 1.6, Essential Content Types WordPress plugin before 1.9, Catch Web Tools WordPress plugin before 2.7, Catch Under Construction WordPress plugin before 1.4, Catch Themes Demo Import WordPress plugin before 1.6, Catch Sticky Menu WordPress plugin before 1.7, Catch Scroll Progress Bar WordPress plugin before 1.6, Social Gallery and Widget WordPress plugin before 2.3, Catch Infinite Scroll WordPress plugin before 1.9, Catch Import Export WordPress plugin before 1.9, Catch Gallery WordPress plugin before 1.7, Catch Duplicate Switcher WordPress plugin before 1.6, Catch Breadcrumb WordPress plugin before 1.7, Catch IDs WordPress plugin before 2.4's configurations.
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-862: Missing Authorization
Reaching this weakness in Catch Duplicate Switcher < 1.6 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Catch Duplicate Switcher the fix is 1.6: builds < 1.6 are affected, anything from 1.6 onward is not.
Remediation
Update to version 1.6, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Catch Duplicate Switcher 1.6 closes this, and updating the plugin is the step that ends it.
