CVE-2026-27265

Victim-browser script execution via stored form input

Published Mar 11, 2026 · Updated Mar 11, 2026

Stored XSS in Adobe Experience Manager 6.5.23 and earlier allows local users with low privileges to execute script in a victim's browser. Affected form fields store attacker-supplied script content without neutralizing it before the page renders the content. Exploitation requires a low-privileged account and a victim to open the page, exposing the victim's browser session to script actions.
