CVE-2021-24614Public exploitNetwork attack vector

Authenticated stored XSS via unescaped Service Prices

Published Sep 13, 2021 · Updated Aug 3, 2024

Stored XSS in oz-plugin OzApp before 1.39 allows remote authenticated users to execute script via a crafted Service Price. The services editor accepts the price request-body field without sanitizing it and renders the stored value unescaped in the services list. A high-privilege account can plant the payload even when unfiltered_html is disabled, and code runs only when another user views the list, enabling browser-session data access or page changes.
