CVE-2025-30592 Overview
CVE-2025-30592 is a Missing Authorization vulnerability in the WesternDeal Advanced Dewplayer plugin for WordPress. The flaw stems from incorrectly configured access control security levels within the plugin. It affects all Advanced Dewplayer versions up to and including 1.6. An unauthenticated attacker can send network requests to plugin endpoints that fail to enforce proper authorization checks. The vulnerability is tracked under CWE-862: Missing Authorization.
Critical Impact
Unauthenticated network-based attackers can access functionality that should require authorization, resulting in limited confidentiality impact on affected WordPress sites running Advanced Dewplayer 1.6 or earlier.
Affected Products
- WesternDeal Advanced Dewplayer WordPress plugin
- Advanced Dewplayer versions from n/a through 1.6
- WordPress sites with the advanced-dewplayer plugin installed and active

Technical Details for CVE-2025-30592
Vulnerability Analysis
The Advanced Dewplayer plugin exposes functionality without validating whether the requesting user has permission to invoke it. This is a Broken Access Control weakness classified as CWE-862 Missing Authorization. The plugin registers handlers accessible to unauthenticated visitors, but those handlers do not perform capability checks or nonce validation before executing privileged actions.
An attacker can reach the vulnerable endpoints over the network without user interaction or prior credentials. The impact is limited to confidentiality, meaning an attacker can read data that should be protected but cannot directly modify site content or disrupt availability through this specific flaw.
Root Cause
The root cause is the absence of authorization enforcement on plugin actions. WordPress plugins typically gate sensitive actions using current_user_can() capability checks and check_admin_referer() or wp_verify_nonce() for request integrity. Advanced Dewplayer through version 1.6 omits these checks on at least one accessible handler, permitting anonymous requests to reach code paths intended for authorized contexts.
Attack Vector
Exploitation occurs over HTTP or HTTPS against the WordPress site hosting the vulnerable plugin. An attacker crafts a request to the exposed plugin endpoint and receives data that should require authorization. No authentication, user interaction, or elevated privileges are required. Because Advanced Dewplayer is an audio player plugin, the exposed data likely relates to media configuration or plugin state. Refer to the Patchstack WordPress Vulnerability Analysis for endpoint-specific technical details.
No public proof-of-concept exploit code has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS score is 0.346%.
Detection Methods for CVE-2025-30592
Indicators of Compromise
- Unauthenticated HTTP requests targeting advanced-dewplayer plugin paths under /wp-content/plugins/advanced-dewplayer/ or the plugin's registered AJAX actions
- Anonymous access to admin-ajax.php with action parameters registered by Advanced Dewplayer
- Unexpected data returned in responses to unauthenticated requests hitting plugin endpoints
Detection Strategies
- Inventory WordPress installations and identify sites running Advanced Dewplayer version 1.6 or earlier by inspecting the plugin's readme.txt or main plugin file header
- Review web server access logs for repeated requests to plugin endpoints originating from unauthenticated sessions
- Deploy WordPress security scanners that reference the Patchstack vulnerability database to flag vulnerable plugin versions
Monitoring Recommendations
- Alert on spikes in admin-ajax.php traffic without corresponding authenticated session cookies
- Monitor outbound data volume from WordPress hosts to identify potential enumeration of plugin data
- Track plugin version drift across managed WordPress fleets to detect installations left on the vulnerable 1.6 release
How to Mitigate CVE-2025-30592
Immediate Actions Required
- Identify all WordPress sites running Advanced Dewplayer version 1.6 or earlier
- Deactivate and remove the plugin if a patched release is unavailable or if the plugin is not essential to site operations
- Apply web application firewall (WAF) rules that block unauthenticated requests to the plugin's endpoints until a fix is applied
Patch Information
At the time of publication, the NVD entry and the Patchstack advisory list affected versions up to and including 1.6 without confirming a fixed release. Site operators should monitor the plugin's WordPress.org listing and the vendor advisory for a patched version and upgrade as soon as it is available.
Workarounds
- Remove or disable the Advanced Dewplayer plugin until an official patch is released
- Restrict access to /wp-content/plugins/advanced-dewplayer/ at the web server or WAF layer for anonymous users
- Enforce plugin auto-updates in wp-config.php so future patched versions install automatically once published
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate advanced-dewplayer
wp plugin uninstall advanced-dewplayer
