At a glance
CVE-2025-13404 is a medium-severity Missing Authorization vulnerability in the atec Duplicate Page & Post WordPress plugin, affecting versions <= 1.2.20. 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 1.2.21; sites on affected versions should update now. Disclosed November 2025, reported by Athiwat Tiprasaharn (Jitlada).
Vulnerability Overview
The atec Duplicate Page & Post plugin for WordPress is vulnerable to unauthorized post duplication due to missing authorization validation on the duplicate_post() function in all versions up to, and including, 1.2.20. This makes it possible for authenticated attackers, with Contributor-level access and above, to duplicate arbitrary posts, including private and password-protected posts, leading to data exposure.
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
atec Duplicate Page & Post <= 1.2.20 carries this weakness at duplicate_post(), and reaching it takes an account at Contributor 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 atec Duplicate Page & Post the fix is 1.2.21: builds <= 1.2.20 are affected, anything from 1.2.21 onward is not.
Remediation
Update to version 1.2.21, 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: atec Duplicate Page & Post 1.2.21 closes this, and updating the plugin is the step that ends it.
