CVE-2026-4063
Received Received - Intake
Unauthorized Data Modification in WPZOOM Social Icons Plugin

Publication date: 2026-03-13

Last updated on: 2026-03-13

Assigner: Wordfence

Description
The Social Icons Widget & Block by WPZOOM plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check in the add_menu_item() method hooked to admin_menu in all versions up to, and including, 4.5.8. This is due to the method performing wp_insert_post() and update_post_meta() calls to create a sharing configuration without verifying the current user has administrator-level capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger the creation of a published wpzoom-sharing configuration post with default sharing button settings, which causes social sharing buttons to be automatically injected into all post content on the frontend via the the_content filter.

Executive Summary

The Social Icons Widget & Block by WPZOOM plugin for WordPress has a vulnerability due to a missing capability check in the add_menu_item() method. This method is hooked to the admin_menu and performs actions like wp_insert_post() and update_post_meta() to create a sharing configuration without verifying if the current user has administrator-level permissions.

As a result, authenticated users with Subscriber-level access or higher can trigger the creation of a published wpzoom-sharing configuration post with default social sharing button settings. This causes social sharing buttons to be automatically injected into all post content on the frontend.

Impact Analysis

This vulnerability allows users with low-level access (Subscriber-level and above) to modify data by creating published sharing configuration posts without proper authorization.

The impact is limited to unauthorized data modification, specifically the automatic injection of social sharing buttons into all post content on the frontend.

The CVSS score of 4.3 indicates a low to medium severity impact, with no confidentiality or availability impact, but with integrity impact due to unauthorized changes.
