CVE-2026-7509

KIA Subtitle <= 4.0.1 - [Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')]

Published May 22, 2026 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed
Description
The KIA Subtitle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `the-subtitle` shortcode `before` and `after` attributes in all versions up to, and including, 4.0.1. This is due to insufficient input sanitization and output escaping on user supplied attributes. 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.
