CVE-2026-1219
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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 summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Sonaar MP3 Audio Player plugin is installedCheck the WordPress plugins directory (wp-content/plugins) for the 'mp3-audio-player' or 'sonaar-mp3-audio-player' folder, or list installed plugins via WordPress admin under Plugins > Installed PluginsAffected if The plugin folder exists in the WordPress plugins directory
-
Determine installed plugin versionView the plugin main file header (usually plugin.php or index.php inside the plugin folder) and locate the 'Version' comment, or check the version displayed in WordPress admin under Plugins > Installed PluginsAffected if Version is 4.0, 4.x, 5.0 through 5.10, or any version within the 4.0 to 5.10 range inclusive
-
Confirm the vulnerable AJAX endpoint existsCheck if the file containing 'load_track_note_ajax' function exists in the plugin directory, or attempt a direct HTTP request to the AJAX endpoint (usually at wp-admin/admin-ajax.php with action=load_track_note_ajax)Affected if The AJAX endpoint responds and the function code is present in the plugin files without proper authorization validation
-
Identify if private posts exist that could be accessedQuery the WordPress database for posts with post_status='private' using SQL: SELECT ID, post_title, post_status FROM wp_posts WHERE post_status='private'Affected if Private posts exist in the database that could be accessed through the unprotected AJAX endpoint
A user is affected if the Sonaar MP3 Audio Player plugin version 4.0 through 5.10 is installed, the vulnerable load_track_note_ajax function is present, and the site contains private posts that could be exposed via the unprotected AJAX endpoint.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the plugin to version 5.11 or later which contains the fix. If an update is unavailable, consider disabling the plugin or implementing web application firewall rules to block unauthorized access to the affected AJAX endpoint.
