CVE-2023-3552Network attack vector

Stored XSS via post-sanitization entity decoding

Published Jul 8, 2023 · Updated Oct 30, 2024

Cross-site scripting in the folder page of Teampass before 3.0.10 allows remote authenticated users to run script via crafted folder data. The simplePurifier function passed text through DOMPurify and then decoded HTML entities, restoring executable markup after sanitization. Exploitation requires low-privileged access and another user to view the affected folder page, exposing browser-accessible data and actions.
