CVE, Research URL: CVE-2026-7509
Home page URL: Security reports for KIA Subtitle
Application: KIA Subtitle
Date: May 22, 2026
Research 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.
Affected versions: max 4.0.2.
Status: vulnerable
