CVE-2022-4558Network attack vector

Cross-site scripting via incomplete mail text sanitization

Published Dec 16, 2022 · Updated Apr 15, 2025

Cross-site scripting in SOGo 5.7.1 and earlier allows remote authenticated users to execute script through crafted folder or mail text. NSString+Utilities.m's stringWithoutHTMLInjection method scans markup and substitutes selected script and event-handler patterns, allowing crafted input to survive the incomplete sanitization. Exploitation requires an authenticated user to supply the content and another user to render it in the web interface, where the script runs in that viewer's browser context.
