CVE-2025-32235 Overview
CVE-2025-32235 is a Missing Authorization vulnerability [CWE-862] in the MP3 Audio Player for Music, Radio & Podcast by Sonaar WordPress plugin (mp3-music-player-by-sonaar). The flaw affects all plugin versions up to and including 5.9.4. Attackers with low-privilege authenticated accounts can exploit incorrectly configured access control security levels to perform actions outside their permission scope. The vulnerability is network-exploitable and requires no user interaction, making it a viable target on multi-user WordPress installations that permit low-tier account registration.
Critical Impact
Authenticated users with minimal privileges can bypass authorization checks and modify plugin data, resulting in limited integrity impact on affected WordPress sites.
Affected Products
- MP3 Audio Player for Music, Radio & Podcast by Sonaar (mp3-music-player-by-sonaar) — versions up to and including 5.9.4
- WordPress installations running the vulnerable plugin
- Multi-user WordPress sites that allow subscriber-level registration

Technical Details for CVE-2025-32235
Vulnerability Analysis
The vulnerability is a Broken Access Control flaw classified under CWE-862: Missing Authorization. The plugin exposes functionality that fails to verify whether the requesting user holds the necessary role or capability to invoke it. As a result, authenticated users with low privileges can trigger actions the plugin intended to restrict to higher-privileged accounts.
The attack vector is network-based, complexity is low, and no user interaction is required. Exploitation requires an authenticated session but does not require administrative rights. The integrity of plugin-managed data is affected, while confidentiality and availability remain intact. According to the Patchstack advisory, the affected code paths lack proper capability checks before performing state-changing operations.
Root Cause
The root cause is the absence of authorization checks within one or more plugin endpoints. WordPress plugins typically enforce access control using current_user_can() capability checks and nonce validation on AJAX or admin-post handlers. In vulnerable versions of mp3-music-player-by-sonaar, these checks are either missing or misconfigured, allowing subscriber-level accounts to reach protected functionality.
Attack Vector
An attacker registers or compromises a low-privilege WordPress account. The attacker then issues an authenticated HTTP request to the vulnerable plugin endpoint. Because the endpoint does not validate the caller's role, the request succeeds and modifies plugin state. The vulnerability does not permit direct code execution or data exfiltration, but it enables unauthorized configuration or content changes within the plugin's scope.
No verified public proof-of-concept code is available. See the Patchstack advisory for the technical writeup.
Detection Methods for CVE-2025-32235
Indicators of Compromise
- Unexpected changes to Sonaar MP3 player playlists, tracks, or plugin settings performed by non-administrator accounts
- Authenticated HTTP POST requests to wp-admin/admin-ajax.php or plugin-specific endpoints originating from subscriber-level user IDs
- New or modified plugin content entries whose author is a low-privilege user account
- Unusual clusters of authenticated requests to mp3-music-player-by-sonaar endpoints from a single session
Detection Strategies
- Review WordPress access logs for requests to plugin endpoints correlated with low-privilege user session cookies
- Enable WordPress audit logging to record capability-check failures and privileged actions performed by subscriber-role users
- Compare plugin configuration snapshots over time to detect unauthorized state changes
Monitoring Recommendations
- Alert on HTTP 200 responses to plugin AJAX endpoints when the requesting user role is subscriber or contributor
- Monitor WordPress database tables associated with the plugin for writes originating outside administrator sessions
- Track spikes in new user registrations followed by immediate requests to plugin endpoints
How to Mitigate CVE-2025-32235
Immediate Actions Required
- Update the MP3 Audio Player for Music, Radio & Podcast by Sonaar plugin to a version later than 5.9.4 as soon as a patched release is available
- Audit existing user accounts and remove unnecessary subscriber or contributor accounts on public-facing WordPress sites
- Disable open user registration on WordPress sites that do not require it via Settings → General → Membership
- Review recent plugin activity logs for unauthorized changes and revert any suspicious modifications
Patch Information
Refer to the Patchstack advisory for mp3-music-player-by-sonaar for the fixed version and vendor-supplied guidance. Apply the update through the WordPress plugin dashboard or via WP-CLI once released.
Workarounds
- Deactivate the mp3-music-player-by-sonaar plugin until a patched version is installed
- Restrict access to WordPress admin AJAX endpoints for low-privilege roles using a web application firewall rule
- Enforce virtual patching through Patchstack or an equivalent WordPress security service that ships mitigation rules for this CVE
# Update the Sonaar MP3 player plugin via WP-CLI once a patched release is available
wp plugin update mp3-music-player-by-sonaar
# Alternative: temporarily deactivate the plugin until patched
wp plugin deactivate mp3-music-player-by-sonaar
# Disable open user registration to reduce the attack surface
wp option update users_can_register 0
