WordPress Plugin Vulnerabilities

Popup Maker < 1.21.0 - Contributor+ Stored XSS via title Parameter

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the ‘title’ parameter due to insufficient input sanitization and output escaping. 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.
