CVE-2025-30915 Overview
CVE-2025-30915 is a missing authorization vulnerability in the Enitureechnology Small Package Quotes – Worldwide Express Edition WordPress plugin. The flaw affects all versions up to and including 5.2.19. The plugin fails to enforce proper access control on one or more endpoints, allowing unauthenticated network attackers to interact with functionality that should be restricted.
The issue is categorized under [CWE-862: Missing Authorization]. Successful exploitation permits limited impact to integrity and availability, without affecting confidentiality.
Critical Impact
Unauthenticated attackers can invoke plugin functionality that lacks proper capability or nonce checks, altering plugin state or triggering shipping-quote actions on affected WordPress sites.
Affected Products
- Enituretechnology Small Package Quotes – Worldwide Express Edition WordPress plugin
- All versions up to and including 5.2.19
- WordPress sites with the small-package-quotes-wwe-edition plugin installed and activated

Technical Details for CVE-2025-30915
Vulnerability Analysis
The vulnerability stems from broken access control in the Small Package Quotes – Worldwide Express Edition plugin. One or more plugin handlers execute privileged actions without verifying the caller's WordPress capabilities or validating a nonce. An unauthenticated request over the network can reach these handlers directly.
Because the attack requires no privileges and no user interaction, exploitation is straightforward once a vulnerable endpoint is identified. The impact is limited to partial integrity and availability changes within the plugin's scope, such as modifying plugin configuration or invoking shipping-quote logic in an unintended context.
The EPSS score is 0.364%, indicating a low current probability of exploitation activity in the wild.
Root Cause
The root cause is the absence of authorization checks on plugin endpoints. WordPress plugins are expected to call current_user_can() and check_ajax_referer() or wp_verify_nonce() before performing state-changing actions. The affected plugin registers AJAX or admin-post handlers that omit these checks, exposing them to any unauthenticated visitor.
Attack Vector
An attacker sends a crafted HTTP request to the vulnerable plugin endpoint on a WordPress site running a vulnerable version. Because there is no authentication requirement, the attacker only needs the site URL and knowledge of the endpoint action name. The handler executes as though the request originated from an authorized administrator, resulting in limited unauthorized modifications.
Refer to the Patchstack advisory for the Small Package Quotes plugin for additional technical context.
Detection Methods for CVE-2025-30915
Indicators of Compromise
- Unexpected POST or GET requests to admin-ajax.php or admin-post.php referencing plugin-specific action parameters from unauthenticated sessions.
- Modified plugin settings or unusual shipping-quote records without a corresponding administrator login event.
- Requests to plugin endpoints originating from IP addresses that never authenticated to wp-login.php.
Detection Strategies
- Inspect web server access logs for requests to plugin endpoints associated with small-package-quotes-wwe-edition that lack a valid WordPress authentication cookie.
- Enumerate installed plugin versions across the estate and flag any instance at or below version 5.2.19.
- Monitor for anomalous WordPress database writes to plugin-owned option keys or custom tables.
Monitoring Recommendations
- Enable WordPress audit logging to record administrative actions and correlate them with authenticated sessions.
- Alert on high-frequency access to admin-ajax.php from single source IPs, especially when tied to unauthenticated actions.
- Track plugin version inventory over time to confirm patch rollout across all WordPress installations.
How to Mitigate CVE-2025-30915
Immediate Actions Required
- Update the Small Package Quotes – Worldwide Express Edition plugin to a version later than 5.2.19 once released by the vendor.
- Audit WordPress installations for the presence of the vulnerable plugin and prioritize public-facing sites first.
- Review plugin-owned settings and recent shipping-quote transactions for unauthorized modifications.
Patch Information
At the time of NVD publication, the vendor advisory referenced by Patchstack lists all versions through 5.2.19 as affected. Administrators should monitor the WordPress plugin repository for a fixed release and apply it as soon as it is available.
Workarounds
- Deactivate and remove the plugin until a patched release is installed if shipping-quote functionality is not business-critical.
- Restrict access to admin-ajax.php and admin-post.php at the web application firewall for plugin-specific action parameters from unauthenticated sources.
- Enforce IP allowlisting on /wp-admin/ and related endpoints for environments where the plugin must remain active.
