CVE-2025-30909 Overview
CVE-2025-30909 is a missing authorization vulnerability in the Conversios.io Enhanced E-commerce for WooCommerce Store plugin for WordPress. The flaw affects all versions up to and including 7.2.3. It stems from incorrectly configured access control security levels, allowing authenticated users with low privileges to invoke functionality that should be restricted. The vulnerability is tracked under CWE-862: Missing Authorization and was disclosed through Patchstack.
Critical Impact
Authenticated attackers with minimal privileges can access restricted plugin functionality, potentially modifying data managed by the Conversios.io integration on affected WooCommerce sites.
Affected Products
- Conversios.io Enhanced E-commerce for WooCommerce Store plugin
- All versions from n/a through 7.2.3
- WordPress sites running the vulnerable plugin with WooCommerce

Technical Details for CVE-2025-30909
Vulnerability Analysis
The Conversios.io plugin exposes plugin actions that lack proper capability or nonce validation. An authenticated user with low privileges, such as a Subscriber or Customer role, can invoke these actions to trigger behavior intended for administrators. The result is a limited integrity impact on data handled by the plugin, without direct effect on confidentiality or availability of the underlying site.
The Patchstack advisory classifies the issue as broken access control. The current EPSS probability is 0.319%, indicating low expected exploitation activity, and no public proof-of-concept or in-the-wild exploitation has been recorded.
Root Cause
The root cause is missing authorization checks on plugin endpoints. Handlers registered by the plugin do not verify the caller's WordPress capability before executing privileged logic. Access control decisions rely on assumptions about who can reach the endpoint rather than explicit current_user_can() checks or nonce verification through check_ajax_referer().
Attack Vector
Exploitation requires an authenticated session on the target WordPress site. Because WooCommerce sites often allow self-registration for customers, the barrier to obtaining a low-privileged account is minimal. The attacker sends crafted HTTP requests to the vulnerable plugin endpoints, invoking actions that should be limited to administrators. No user interaction is required beyond the attacker's own request.
No verified exploit code is available for this vulnerability. Refer to the Patchstack Vulnerability Report for additional technical detail.
Detection Methods for CVE-2025-30909
Indicators of Compromise
- Unexpected changes to Conversios.io plugin settings or Google Analytics configuration stored by the plugin.
- WordPress admin-ajax.php or REST API requests referencing Conversios.io actions originating from low-privileged user sessions.
- New or modified plugin option entries in the wp_options table associated with the enhanced-e-commerce-for-woocommerce-store plugin.
Detection Strategies
- Review WordPress access logs for POST requests to plugin AJAX handlers made by non-administrator user IDs.
- Correlate authenticated session activity from Subscriber or Customer accounts with requests targeting administrative plugin endpoints.
- Enable WordPress audit logging plugins to record plugin setting changes and identify actors performing them.
Monitoring Recommendations
- Monitor plugin version inventory across managed WordPress installations to confirm upgrades past 7.2.3.
- Alert on new user registrations followed by immediate requests to plugin action endpoints.
- Track outbound requests generated by the plugin for anomalies suggesting configuration tampering.
How to Mitigate CVE-2025-30909
Immediate Actions Required
- Update the Conversios.io Enhanced E-commerce for WooCommerce Store plugin to a version later than 7.2.3 as soon as a fixed release is available.
- Audit existing WordPress user accounts and remove unused low-privileged accounts that could be leveraged for exploitation.
- Review plugin settings for unauthorized modifications and restore known-good configurations.
Patch Information
At the time of publication, the Patchstack advisory lists the issue as affecting versions up to and including 7.2.3. Consult the Patchstack Vulnerability Report and the plugin's WordPress.org listing for the latest patched release.
Workarounds
- Temporarily deactivate the Conversios.io plugin until a patched version is installed.
- Disable open user registration on the WordPress site to reduce the population of authenticated attackers.
- Deploy a web application firewall rule to block requests to the vulnerable plugin action endpoints from non-administrator sessions.
# Configuration example: disable open registration and restrict plugin endpoints
wp option update users_can_register 0
wp plugin deactivate enhanced-e-commerce-for-woocommerce-store
