CVE-2024-22075Public exploitNetwork attack vector

HTML injection via client-side path traversal

Published Jan 5, 2024 · Updated Jun 5, 2025

HTML injection in Firefly III before 6.1.1 allows remote attackers to inject HTML or CSS through a crafted webhook-edit URL. The webhook editor derives an API path from the final URL segment without validation, then renders a reflected error message as raw HTML through Vue's v-html directive. Exploitation requires an authenticated victim to open the link and at least one configured webhook; the default content security policy blocks script execution, but redirects, deceptive UI, and CSS-based data disclosure remain possible.
