CVE-2023-3083Network attack vector

Stored script execution via insufficient user-field validation

Published Jun 3, 2023 · Updated Feb 12, 2025

Stored cross-site scripting in Teampass before 3.0.9 allows remote authenticated users to execute script through crafted user profile fields. The user-management form saved login, first-name, last-name, and email values after DOMPurify processing that did not apply the stricter fieldSanitizeStep1 validation added by the fix. A privileged account must save the payload and another user must view the affected content; execution in that user's browser can read or alter data available to the session.
