CVE-2025-1507: ShareThis Dashboard Auth Bypass Flaw

CVE-2025-1507 Overview

CVE-2025-1507 affects the ShareThis Dashboard for Google Analytics plugin for WordPress in all versions up to and including 3.2.1. The plugin exposes the handle_actions() function without a capability check, allowing unauthenticated attackers to invoke privileged actions. Successful exploitation lets attackers disable plugin features across the affected site. The flaw maps to Missing Authorization [CWE-862] and is exploitable over the network without authentication or user interaction.

Critical Impact
Unauthenticated network attackers can modify plugin state and disable all ShareThis Dashboard for Google Analytics features on affected WordPress sites.

Affected Products

Technical Details for CVE-2025-1507

Vulnerability Analysis

The vulnerability stems from a missing capability check inside the handle_actions() function in the plugin's core controller. WordPress plugins typically gate administrative actions with current_user_can() checks and nonce verification. The affected code path performs neither check before executing state-changing operations. Any unauthenticated visitor can trigger these actions by sending a crafted HTTP request.

The practical outcome is limited to integrity impact. Attackers can toggle or disable plugin functionality but cannot read protected data or exhaust availability of the wider site. Disabling the analytics integration breaks reporting workflows for site administrators. Automated scanners frequently sweep WordPress installations for authorization flaws in installed plugins, so exposure risk is elevated even for low-traffic sites.

Root Cause

The root cause is Missing Authorization [CWE-862] in the handle_actions() handler within class-ga-controller-core.php. The function processes user-supplied action parameters without verifying the caller's WordPress role or a valid nonce. The vendor patch adds the required capability check, as shown in the WordPress Changeset Update.

Attack Vector

An attacker sends an unauthenticated HTTP request to the WordPress site targeting the plugin's action handler endpoint. The request carries parameters that invoke feature-toggling logic inside handle_actions(). Because no capability check occurs, the plugin executes the requested change and persists it to the site database. Refer to the Wordfence Vulnerability Report for additional technical detail.

Detection Methods for CVE-2025-1507

Indicators of Compromise

Unexpected changes to ShareThis Dashboard for Google Analytics plugin settings in the WordPress database
Analytics dashboard features silently disabled without administrator action
HTTP requests from unauthenticated sources targeting the plugin's admin-ajax or action endpoints

Detection Strategies

Inventory WordPress installations for the ShareThis Dashboard for Google Analytics plugin at version 3.2.1 or earlier
Review web server access logs for anonymous POST requests referencing plugin action parameters
Compare current plugin option values against known-good baselines to detect unauthorized toggles

Monitoring Recommendations

Alert on WordPress options table writes originating from unauthenticated sessions
Monitor plugin configuration changes through a file integrity and database change monitoring workflow
Correlate WAF logs for repeated requests to plugin controller endpoints from a single source

How to Mitigate CVE-2025-1507

Immediate Actions Required

Update the ShareThis Dashboard for Google Analytics plugin to the version published after changeset 3255511
Audit plugin settings and restore any values altered without administrator approval
Restrict access to WordPress admin-ajax endpoints from untrusted networks where feasible

Patch Information

The vendor patch is available in the WordPress plugin repository. The fix introduces a capability check inside the handle_actions() function in class/core/class-ga-controller-core.php. Review the code change in the WordPress Changeset Update and update to the corresponding release.

Workarounds

Deactivate the ShareThis Dashboard for Google Analytics plugin until the patched release is applied
Deploy a Web Application Firewall (WAF) rule to block unauthenticated requests to the plugin's action endpoints
Limit access to WordPress administrative paths to trusted IP ranges through the web server configuration

bash

# Example nginx rule to block unauthenticated access to the plugin action handler
location ~* /wp-admin/admin-ajax\.php$ {
    if ($http_cookie !~* "wordpress_logged_in") {
        return 403;
    }
}
