Published Oct 8, 2025 · Updated Oct 8, 2025

Stored XSS in Liferay Forms in Portal 7.3.2 through 7.4.3.111 and affected DXP releases allows remote attackers to inject script through rich text fields. Forms stores crafted HTML supplied to a rich text field and later renders it without sufficient neutralization when a user views the form entry. Exploitation is unauthenticated but requires a user to view the stored entry; script execution can read or alter data in that user's browser context.
