At a glance
CVE-2025-1666 is a medium-severity Missing Authorization vulnerability in the Cookiebot by Usercentrics WordPress plugin, affecting versions <= 4.4.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 4.4.2; sites on affected versions should update now. Disclosed March 2025, reported by Peter Thaleikis.
Vulnerability Overview
The Cookie banner plugin for WordPress – Cookiebot CMP by Usercentrics plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the send_uninstall_survey() function in all versions up to, and including, 4.4.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to submit the uninstall survey on behalf of a website.
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
Cookiebot by Usercentrics <= 4.4.1 carries this weakness at send_uninstall_survey(), and reaching it takes an account at Subscriber level or above. 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 Cookiebot by Usercentrics the fix is 4.4.2: builds <= 4.4.1 are affected, anything from 4.4.2 onward is not.
Remediation
Update to version 4.4.2, 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: Cookiebot by Usercentrics 4.4.2 closes this, and updating the plugin is the step that ends it.
