CVE-2024-22291
At a glance
CVE-2024-22291 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Browser Theme Color WordPress plugin, affecting versions <= 1.3. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 1.4; sites on affected versions should update now. Disclosed January 2024, reported by Nguyen Xuan Chien.
Vulnerability Overview
The Browser Theme Color plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3. This is due to missing or incorrect nonce validation on the 'btc_settings_page' function. This makes it possible for unauthenticated attackers to modify the plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
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 privileges on the target site. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Browser Theme Color <= 1.3 carries this weakness at btc_settings_page, and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Browser Theme Color the fix is 1.4: builds <= 1.3 are affected, anything from 1.4 onward is not.
Remediation
Update to version 1.4, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Browser Theme Color: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Browser Theme Color 1.4 closes this, and updating the plugin is the step that ends it.
