AI-suggested
The vulnerability is patched in STIG Manager version 1.6.8. Users should upgrade to this version to fully remediate the issue. There is no known workaround other than upgrading. Deployments using web application firewalls that filter reflected XSS payloads in query parameters may experience partial mitigation, but this does not replace the need to apply the official fix.
Description
STIG Manager versions 1.5.10 through 1.6.7 contain a reflected Cross-Site Scripting (XSS) vulnerability in the OIDC authentication error handling code. The vulnerability arises because the 'error' and 'error_description' query parameters are inserted into the DOM without proper HTML escaping, allowing execution of arbitrary JavaScript. This is particularly dangerous if the user has an active STIG Manager session in another tab, as the injected script can interact with the SharedWorker managing authentication tokens, enabling unauthorized API requests. The issue is fixed in version 1.6.8.
