CVE-2025-39388: AnalyticsWP Auth Bypass Vulnerability

CVE-2025-39388 Overview

CVE-2025-39388 is a missing authorization vulnerability in the Solid Plugins AnalyticsWP plugin for WordPress. The flaw affects all versions of AnalyticsWP up to and including 2.0.0. It allows unauthenticated attackers to access plugin functionality that is not properly constrained by access control lists (ACLs). The issue is tracked under CWE-862: Missing Authorization.

The vulnerability is exploitable remotely over the network without user interaction or prior authentication. Impact is limited to integrity, with no direct confidentiality or availability consequences per the published CVSS vector.

Critical Impact
Unauthenticated attackers can invoke privileged AnalyticsWP functionality on affected WordPress sites, potentially modifying analytics data or plugin state.

Technical Details for CVE-2025-39388

Vulnerability Analysis

CVE-2025-39388 is a broken access control weakness in AnalyticsWP. The plugin exposes one or more actions or endpoints without verifying whether the requesting user holds the required capability or role. WordPress plugins typically enforce access via current_user_can() checks, nonce validation, and capability gating on admin-ajax.php or REST routes. When these checks are missing, any visitor can reach handler code that should be restricted to administrators.

The vulnerability falls under CWE-862 (Missing Authorization). According to the Patchstack advisory, the flaw is classified as a broken access control issue affecting AnalyticsWP through version 2.0.0. Successful requests do not require authentication, which enlarges the attack surface to any client capable of reaching the target site.

Root Cause

The root cause is the absence of authorization checks in one or more plugin request handlers. The plugin registers callbacks that execute privileged operations but does not confirm the caller's identity or capabilities before proceeding. This pattern typically appears when developers omit current_user_can() or fail to attach wp_verify_nonce() checks to AJAX or REST endpoints.

Attack Vector

An attacker sends crafted HTTP requests directly to the vulnerable plugin endpoints on a target WordPress site. No credentials, session, or user interaction are required. The attacker can trigger the affected functionality repeatedly to alter plugin behavior or associated analytics data. Refer to the Patchstack Vulnerability Report for the specific endpoint details.

Detection Methods for CVE-2025-39388

Indicators of Compromise

Unauthenticated POST or GET requests to AnalyticsWP AJAX actions under /wp-admin/admin-ajax.php or plugin-specific REST routes.
Unexpected changes to AnalyticsWP settings, dashboards, or stored analytics records without a corresponding admin login event.
Repeated requests from a single IP targeting plugin action parameters associated with analyticswp.

Detection Strategies

Review WordPress access logs for requests referencing AnalyticsWP action names originating from unauthenticated sessions.
Correlate plugin configuration changes with authenticated administrator activity to identify anomalous modifications.
Deploy a web application firewall (WAF) rule set that flags calls to AnalyticsWP endpoints from clients lacking valid wordpress_logged_in_* cookies.

Monitoring Recommendations

Enable verbose logging on admin-ajax.php and WordPress REST API endpoints for the duration of remediation.
Alert on HTTP 200 responses to AnalyticsWP endpoints from clients without an authenticated session.
Monitor plugin file integrity and database tables used by AnalyticsWP for unauthorized writes.

How to Mitigate CVE-2025-39388

Immediate Actions Required

Update AnalyticsWP to a version later than 2.0.0 as soon as the vendor publishes a patched release.
If no patch is available, deactivate and remove the AnalyticsWP plugin until a fix is released.
Audit recent AnalyticsWP-related requests in web server logs to identify any exploitation attempts.

Patch Information

At the time of publication, the Patchstack Vulnerability Report lists the vulnerability as affecting AnalyticsWP through 2.0.0. Site administrators should consult the vendor page and Patchstack for the latest fixed version. Apply updates through the WordPress plugin manager or WP-CLI once the patched release is available.

Workarounds

Restrict access to /wp-admin/admin-ajax.php and REST endpoints associated with AnalyticsWP via a WAF or reverse proxy rule.
Require authentication at the web server layer for plugin-specific paths until the plugin is updated or removed.
Use a WordPress security plugin to virtually patch missing capability checks on AnalyticsWP actions.

bash

# Configuration example: disable AnalyticsWP via WP-CLI until patched
wp plugin deactivate analyticswp
wp plugin uninstall analyticswp
