At a glance
CVE-2026-1219 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the MP3 Audio Player WordPress plugin, affecting versions 4.0 – 5.10. 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 5.11; sites on affected versions should update now. Disclosed February 2026, reported by kr0d.
Vulnerability Overview
The MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions 4.0 to 5.10 via the 'load_track_note_ajax' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view the contents of private posts.
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-639: Authorization Bypass Through User-Controlled Key
MP3 Audio Player 4.0 – 5.10 carries this weakness at load_track_note_ajax, and reaching it takes no account at all. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For MP3 Audio Player the fix is 5.11: builds 4.0 – 5.10 are affected, anything from 5.11 onward is not.
Remediation
Update to version 5.11, 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: MP3 Audio Player 5.11 closes this, and updating the plugin is the step that ends it.
