At a glance
CVE-2026-1644 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the WP Frontend Profile WordPress plugin, affecting versions <= 1.3.8. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.3.9; sites on affected versions should update now. Disclosed March 2026, reported by johska.
Vulnerability Overview
The WP Frontend Profile plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.8. This is due to missing nonce validation on the 'update_action' function. This makes it possible for unauthenticated attackers to approve or reject user account registrations via a forged request granted they can trick an 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.
CWE-352: Cross-Site Request Forgery (CSRF)
WP Frontend Profile <= 1.3.8 carries this weakness at update_action, 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 WP Frontend Profile the fix is 1.3.9: builds <= 1.3.8 are affected, anything from 1.3.9 onward is not.
Remediation
Update to version 1.3.9, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to WP Frontend Profile: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Frontend Profile 1.3.9 closes this, and updating the plugin is the step that ends it.
