CVE-2025-32239 Overview
CVE-2025-32239 is a Missing Authorization vulnerability [CWE-862] in the Joao Romao Social Share Buttons & Analytics Plugin – GetSocial.io (wp-share-buttons-analytics-by-getsocial) for WordPress. The flaw affects all plugin versions up to and including 4.5. Authenticated attackers with low privileges can exploit incorrectly configured access control checks to perform actions restricted to higher-privileged users. The issue stems from missing capability validation in one or more plugin request handlers.
Critical Impact
Authenticated low-privilege users can bypass access control checks in the GetSocial WordPress plugin, potentially modifying plugin state or exposing limited integrity impact on the site.

Technical Details for CVE-2025-32239
Vulnerability Analysis
The vulnerability is a broken access control issue in the GetSocial WordPress plugin. The plugin exposes functionality without validating whether the requesting user holds the appropriate WordPress capability. An attacker who is authenticated as a low-privilege user, such as a subscriber, can invoke plugin actions that should be restricted to administrators or editors.
The attack requires network access to the WordPress site and low-privilege authentication. No user interaction is required. The impact is limited to integrity of plugin-controlled data. Confidentiality and availability are not directly impacted based on the CVSS vector.
The CWE classification [CWE-862] indicates that the affected code paths do not perform authorization checks such as current_user_can() before executing sensitive operations. This pattern is common in WordPress plugins that add AJAX handlers or admin-post endpoints without gating them behind capability checks.
Root Cause
The root cause is missing authorization logic in plugin request handlers. Functions that modify plugin settings or state accept requests from any authenticated user rather than verifying WordPress role capabilities. Nonce checks alone, if present, do not enforce authorization because any logged-in user can obtain a valid nonce.
Attack Vector
Exploitation requires an attacker to hold a valid WordPress account on the target site, even at the lowest privilege level. The attacker sends crafted HTTP requests to vulnerable plugin endpoints such as admin-ajax.php actions registered by wp-share-buttons-analytics-by-getsocial. Because the endpoints do not verify user capabilities, the plugin processes the request and applies the requested state change. See the Patchstack Vulnerability Report for advisory details.
No public proof-of-concept exploit or Exploit-DB entry is currently listed for this CVE. The EPSS probability is 0.422% with a percentile of 35.274 as of 2026-09-01.
Detection Methods for CVE-2025-32239
Indicators of Compromise
- Unexpected POST requests to admin-ajax.php with action parameters registered by the GetSocial plugin originating from low-privilege user sessions.
- Modifications to GetSocial plugin options in the wp_options table performed outside of administrator sessions.
- New or altered social share configurations that do not correlate with administrator activity in the WordPress audit log.
Detection Strategies
- Review WordPress access logs for authenticated requests to plugin AJAX endpoints from users whose role does not match the action performed.
- Correlate WordPress user session data with plugin configuration change events to identify privilege boundary violations.
- Deploy a WordPress security plugin or Web Application Firewall (WAF) rule that alerts on subscriber-level requests to administrative plugin actions.
Monitoring Recommendations
- Enable verbose logging on admin-ajax.php and admin-post.php and forward events to a centralized SIEM for correlation.
- Monitor changes to the wp_options table and file modifications inside wp-content/plugins/wp-share-buttons-analytics-by-getsocial/.
- Track newly registered low-privilege accounts followed by requests to plugin management endpoints.
How to Mitigate CVE-2025-32239
Immediate Actions Required
- Audit installed WordPress sites for the wp-share-buttons-analytics-by-getsocial plugin and identify any version at or below 4.5.
- Deactivate the GetSocial plugin on affected sites until a fixed release is installed.
- Review WordPress user accounts and remove or downgrade any unexpected subscriber or contributor accounts.
Patch Information
At the time of publication, the vendor advisory tracked by Patchstack indicates the vulnerability affects all versions up to and including 4.5. Administrators should consult the Patchstack Vulnerability Report for the current fixed version and upgrade to the latest available release from the WordPress plugin repository.
Workarounds
- Restrict access to wp-admin/admin-ajax.php for unauthenticated and low-privilege users via WAF rules where feasible.
- Disable open user registration to limit the pool of authenticated attackers.
- Remove the plugin entirely and replace it with a maintained alternative if a patch is unavailable.
# Disable open WordPress registration via wp-cli
wp option update users_can_register 0
# Deactivate the affected plugin
wp plugin deactivate wp-share-buttons-analytics-by-getsocial
