Technical details
A stored cross-site scripting (XSS) vulnerability exists in JetElements for Elementor versions up to 2.9.2.1 due to insufficient input sanitization and output encoding. The vulnerability allows a user with Contributor-level privileges to inject malicious JavaScript code that persists in the database and executes in the browsers of administrators or other users who view the affected content. Exploitation requires a privileged user (contributor) to create or edit content with embedded malicious payloads, but execution occurs when higher-privilege users access that content. The vulnerability was patched in version 2.9.2.2. Users should upgrade immediately to mitigate the risk of session hijacking, credential theft, or malware distribution.
