At a glance
CVE-2026-1280 is a high-severity Missing Authorization vulnerability in the Frontend File Manager Plugin WordPress plugin, affecting versions <= 23.5. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 23.6; sites on affected versions should update now. Disclosed January 2026, reported by Md. Moniruzzaman Prodhan (NomanProdhan).
Vulnerability Overview
The Frontend File Manager Plugin for WordPress is vulnerable to unauthorized file sharing due to a missing capability check on the 'wpfm_send_file_in_email' AJAX action in all versions up to, and including, 23.5. This makes it possible for unauthenticated attackers to share arbitrary uploaded files via email by supplying a file ID. Since file IDs are sequential integers, attackers can enumerate all uploaded files on the site and exfiltrate sensitive data that was intended to be restricted to administrators only.
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. A successful exploit has high impact on confidentiality.
CWE-862: Missing Authorization
Frontend File Manager Plugin <= 23.5 carries this weakness at wpfm_send_file_in_email, 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 Frontend File Manager Plugin the fix is 23.6: builds <= 23.5 are affected, anything from 23.6 onward is not.
Remediation
Update to version 23.6, 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: Frontend File Manager Plugin 23.6 closes this, and updating the plugin is the step that ends it.
