CVE-2022-30578Network attack vector

Authenticated browser script execution via stored input

Published Sep 21, 2022 · Updated May 28, 2025

Stored XSS in the Web Server component of TIBCO EBX Add-ons 5.4.1 and earlier allows remote authenticated users to execute scripts. TIBCO has not disclosed which Web Server input is stored or where output neutralization fails before the content is rendered. A low-privileged account with network access can plant the payload, and a different user must view the affected content before the script runs in that user's browser.
