Browser script execution via stored form input
Published Jun 28, 2021 · Updated Sep 17, 2024
Stored XSS in Adobe Experience Manager affected releases allows remote authenticated users to execute JavaScript in a victim's browser. Vulnerable form fields retain attacker-supplied script content without neutralizing it, and a later page view sends that content to the browser for execution. The attacker requires low privileges to submit the field content, and a victim must visit the affected page; execution remains confined to that browser context.
