CVE-2023-33438Public exploitNetwork attack vector

Stored script execution via unneutralized TeamStore fields

Published Jun 16, 2023 · Updated Jul 9, 2026

Stored XSS in Wolters Kluwer TeamMate+ 35.0.11.0 allows remote authenticated users to execute script in another user's browser. TeamStore saves HTML event-handler payloads without neutralization in multiple description, definition, finding, and recommendation fields, then renders the stored values to later viewers. A low-privileged account that can create or edit those records can run JavaScript in another user's session, enabling browser-context data access or actions.
