Smart PopUp Blaster <= 1.4.3 - Authenticated (Contributor+) Stored Cross-Site Scripting

Published Dec 6, 2024 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The Smart PopUp Blaster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's
'spb-button' shortcode in all versions up to, and including, 1.4.3 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.
