CVE-2026-8895
Received Received - Intake
Stored XSS in KK Blog Card WordPress Plugin

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: Wordfence

Description
The kk blog card plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'blog-card' shortcode in all versions up to, and including, 1.3. This is due to insufficient input sanitization and output escaping on the shortcode's 'href' and 'type' attributes, which are concatenated directly into HTML attribute contexts in the shortcode callback registered in kk-blog-card-shortcode.php. 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 kk blog card plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its 'blog-card' shortcode in all versions up to and including 1.3.

This vulnerability arises because the plugin does not properly sanitize or escape input for the 'href' and 'type' attributes, which are directly inserted into HTML attributes.

As a result, authenticated users with contributor-level access or higher can inject malicious scripts that execute whenever someone views the affected page.

Impact Analysis

This vulnerability allows attackers with contributor-level access to inject arbitrary scripts into pages, which can execute in the browsers of users who visit those pages.

Such script execution can lead to theft of user credentials, session hijacking, defacement, or other malicious actions impacting the website's users and integrity.

Because the attack requires authenticated access, it may be exploited by insiders or compromised accounts.
