Victim-browser script execution via unsanitized form fields
Published Dec 10, 2025 · Updated Dec 10, 2025
Stored XSS in Adobe Experience Manager 6.5.23 and earlier allows remote authenticated users to execute scripts in a victim's browser. Vulnerable form fields accept and store attacker-supplied script content without neutralizing it, then render that content when another user opens the affected page. Low-privileged access is required to plant the payload, and execution requires a victim to browse to the page; resulting script access is limited to the victim's browser context.
