CVE-2025-13989WP Dropzone <= 1.1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'callback' Shortcode Attribute
Medium 6.4
In plain English
A medium-severity cross-site scripting in WP Dropzone from nazsabuz. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 21% of all known vulnerabilities).
Official description
The WP Dropzone plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'callback' shortcode attribute in all versions up to, and including, 1.1.1. This is due to insufficient input sanitization and output escaping on user-supplied 'callback' attributes, which are evaluated as JavaScript code via the `new Function()` constructor. 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.
