CVE-2022-36033Network attack vector

Cross-site scripting via unsafe relative-link sanitization

Published Aug 29, 2022 · Updated Apr 22, 2025

Cross-site scripting in jsoup before 1.15.3 allows remote attackers to execute script via crafted javascript URLs when users click links. The Cleaner mishandles control characters in javascript: URLs when SafeList.preserveRelativeLinks is enabled, allowing dangerous links to survive sanitization. Exploitation requires a site that accepts attacker HTML, uses that non-default option, lacks an effective Content Security Policy, and has a reader click the persisted link.
