Stored XSS via nonce-free settings update
Published Jun 27, 2022 · Updated Aug 3, 2024
Cross-site request forgery in John Miedema OpenBook Book Data 3.5.2 and earlier allows remote attackers to plant stored script payloads. The settings endpoint accepts cross-origin POST requests without a nonce and writes unvalidated template fields that are later rendered without escaping. Exploitation requires a logged-in administrator to load the crafted form; injected code then runs in browsers that render the poisoned template.
