CVE-2022-31048Network attack vector

Stored XSS via HTML-rendered form labels

Published Jun 14, 2022 · Updated Apr 23, 2025

Stored XSS in TYPO3 CMS before 8.7.47, 9.5.35, 10.4.29, and 11.5.11 allows remote authenticated users to execute script. The Form Designer's stage-component.js inserts multivalue labels and identifiers into preview elements as HTML rather than text, allowing markup to become executable code. Exploitation requires a backend account with Form module access and another user's interaction, exposing data and actions available to that user's browser session.
