CVE-2026-8679
At a glance
CVE-2026-8679 is a high-severity Authorization Bypass Through User-Controlled Key vulnerability in the AudioIgniter Music Player WordPress plugin, affecting versions <= 2.0.2. 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 2.0.3; sites on affected versions should update now. Disclosed May 2026, reported by nudien udin.
Vulnerability Overview
The AudioIgniter plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 2.0.2. This is due to the handle_playlist_endpoint() function (hooked to template_redirect) accepting a user-controlled playlist ID via the audioigniter_playlist_id query var or the /audioigniter/playlist/{id}/ rewrite rule and returning playlist track data without performing any authentication, capability, or post_status check — only the post_type is validated. This makes it possible for unauthenticated attackers to view track metadata (titles, artists, audio URLs, buy links, download URLs, and cover images) of any playlist on the site, including those in draft, private, pending, or trash status.
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-639: Authorization Bypass Through User-Controlled Key
AudioIgniter Music Player <= 2.0.2 carries this weakness at handle_playlist_endpoint(), 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 AudioIgniter Music Player the fix is 2.0.3: builds <= 2.0.2 are affected, anything from 2.0.3 onward is not.
Remediation
Update to version 2.0.3, 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: AudioIgniter Music Player 2.0.3 closes this, and updating the plugin is the step that ends it.
