CVE-2022-36107Network attack vector

Stored XSS via missing CSP on streamed files

Published Sep 13, 2022 · Updated Apr 23, 2025

Stored cross-site scripting in TYPO3 CMS allows remote authenticated users to run script in a victim's browser through FileDumpController. The controller streams attacker-controlled files from backend or frontend contexts without the web server's restrictive Content-Security-Policy. A valid backend account is required to supply malicious file content, and a victim must display the file; impact is limited to browser-context data access or modification.
