CVE-2023-27092Public exploitNetwork attack vector

Sensitive information disclosure via stored username script

Published Apr 18, 2023 · Updated Feb 6, 2025

Stored cross-site scripting in Jbootfly allows remote attackers to read sensitive information through a crafted username. The registration flow stores a username containing script markup without XSS filtering, and the front end later renders that value as active page content. Exploitation requires a user to view the stored profile data, where the injected script runs in that user's browser and can read information available to the page.
