CVE-2023-2516Public exploitNetwork attack vector

Script execution via unsanitized stored item names

Published May 5, 2023 · Updated Feb 12, 2025

Stored XSS in item names in Teampass before 3.0.7 allows remote attackers to execute script in another user's browser. The item editor stores the label without DOMPurify sanitization, allowing markup in a saved item name to reach later folder views. Exploitation requires another user to view the affected folder; script execution can expose or modify data available to that user's session.
