At a glance
CVE-2025-12665 is a medium-severity Missing Authorization vulnerability in the Ninja Countdown WordPress plugin, affecting versions <= 1.5.0. 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. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2025, reported by Ivan Cese.
Vulnerability Overview
The Ninja Countdown | Fastest Countdown Builder plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'ninja_countdown_admin_ajax' AJAX endpoint in all versions up to, and including, 1.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary countdowns.
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
Ninja Countdown <= 1.5.0 carries this weakness at ninja_countdown_admin_ajax, 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. No fixed build of this plugin is recorded for Ninja Countdown yet, so installs running <= 1.5.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
