Description
The Popup Builder – Create highly converting, mobile friendly marketing popups. plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'sg_popup' shortcode in all versions up to, and including, 4.4.1 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.
Weaknesses (CWE)
- CWE-79 — Improper Neutralization of Input During Web Page Generation
