CVE-2026-8842
Deferred Deferred - Pending Action
Stored XSS in Google+ Link Name WordPress Plugin

Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: Wordfence

Description
The Google+ Link Name plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gplusnamelink' shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes ('id' and 'name') in the gplusnamelink_generate() function, which are concatenated directly into the rendered HTML without calling esc_attr() or esc_html(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

The Google+ Link Name plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 1.0. This occurs because the plugin does not properly sanitize or escape user-supplied attributes ('id' and 'name') in the gplusnamelink_generate() function. These attributes are directly inserted into the HTML output without using proper escaping functions, allowing authenticated users with contributor-level access or higher to inject malicious scripts. These scripts execute whenever any user views the affected page.

Impact Analysis

This vulnerability allows attackers with contributor-level access to inject arbitrary scripts into pages, which will execute in the browsers of users who visit those pages. This can lead to unauthorized actions such as stealing user credentials, session hijacking, defacement, or spreading malware. Because the attack is stored, the malicious script persists and affects all users who access the compromised content.
