Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the WordPress plugin 'Social Media Share Buttons & Social Sharing Icons' before version 3.0.1. The flaw occurs because the plugin does not escape the post title before using it in an inline JavaScript event handler. This allows users with the Contributor role or higher to inject malicious scripts that execute when visitors interact with the social sharing buttons.

Detection Guidance

Check if the Social Media Share Buttons & Social Sharing Icons WordPress plugin is installed and its version is below 3.0.1. Look for non-default icon display configurations in the plugin settings.

Impact Analysis

Attackers with Contributor access or higher can inject malicious scripts into posts or pages. When visitors interact with the affected social sharing buttons, the injected scripts execute in their browsers, potentially stealing session cookies, redirecting to malicious sites, or performing actions on behalf of the user.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR and HIPAA compliance. Stored XSS may enable attackers to exfiltrate sensitive user data, such as personal information or protected health data, leading to legal penalties and reputational damage.

Mitigation Strategies

Update the Social Media Share Buttons & Social Sharing Icons plugin to version 3.0.1 or later immediately. If updating is not possible, disable the plugin or remove it from your WordPress installation.
