CVE-2022-36108Network attack vector

Cross-site scripting via unescaped CSS variables

Published Sep 13, 2022 · Updated Apr 23, 2025

Cross-site scripting in TYPO3 CMS 10.3.0 through 10.4.31 and 11.0.0 through 11.5.15 allows remote authenticated users to run script. Fluid's f:asset.css view helper disables child escaping, so child-node variables enter inline style content without HTML encoding. Exploitation requires a low-privileged user to supply a crafted CSS variable and another user to render the page, allowing script execution in that user's browser.
