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 · moderate confidence

This is a stored Cross-Site Scripting (XSS) vulnerability in the SinaExtra extension for the Elementor page builder plugin for WordPress. The vulnerability exists in web page generation functions where user-supplied input is not properly sanitized before being rendered in the output HTML, allowing an attacker to inject malicious JavaScript code that executes when other users view the affected pages.

MitigationUpdate Sina Extension for Elementor to a version newer than 3.5.0 if available, or implement proper input sanitization and output encoding at all points where user input is reflected in the plugin's frontend output.
