Victim-browser script execution via stored form input
Published Jun 9, 2026 · Updated Jun 9, 2026
Stored XSS in Adobe Experience Manager Forms on JEE LTS SP1 and earlier, and 6.5.24.0 and earlier, allows remote attackers to execute browser scripts. Adobe identifies vulnerable form fields as the storage locus but has not disclosed the specific field or the missing validation or output-encoding operation that later renders attacker-controlled script. No authentication is required, but execution occurs only when a victim opens the page containing the poisoned field; the script can act within the victim's account or session without interrupting the service.
