CVE-2023-2021Public exploitNetwork attack vector

Stored script execution via unsanitized folder description

Published Apr 13, 2023 · Updated Feb 6, 2025

Stored cross-site scripting in Teampass before 3.0.3 allows attackers to execute script in another user's browser via a folder description. The description path stores user-controlled markup and renders it to other users without neutralizing executable HTML; the patch adds anti-XSS filtering. Attackers must be able to set the description, and exploitation completes only when another user views the stored content in the Teampass origin.
