Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Elementor Website Builder Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Media Carousel widget in all versions up to, and including, 3.20.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Elementor Website Builder Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting in the Media Carousel widget. Authenticated attackers with contributor-level or higher permissions can inject malicious JavaScript through unsanitized user-supplied attributes in the widget. The injected scripts persist and execute whenever users access the compromised pages.

MitigationUpdate Elementor Website Builder Pro to version 3.20.2 or later which includes proper input sanitization and output escaping. Until patched, review pages using the Media Carousel widget for suspicious content and consider limiting contributor-level publishing capabilities.
