At a glance
CVE-2025-12895 is a medium-severity Missing Authorization vulnerability in the Kalium 3 WordPress theme, affecting versions <= 3.29. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.30; sites on affected versions should update now. Disclosed January 2026, reported by Ahmed Rayen Ayari.
Vulnerability Overview
The Kalium 3 | Creative WordPress & WooCommerce Theme theme for WordPress is vulnerable to unauthorized email sending due to a missing capability check on the kalium_vc_contact_form_request() function in all versions up to, and including, 3.29. This makes it possible for unauthenticated attackers to use the theme an an open mail relay and send email to arbitrary email addresses on the server's behalf.
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, and no interaction from a victim user.
CWE-862: Missing Authorization
Kalium 3 <= 3.29 carries this weakness at kalium_vc_contact_form_request(), and reaching it takes no account at all. 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 Kalium 3 the fix is 3.30: builds <= 3.29 are affected, anything from 3.30 onward is not.
Remediation
Update to version 3.30, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Kalium 3 3.30 closes this, and updating the theme is the step that ends it.
