Stored XSS via malicious forum poll
Published Sep 5, 2022 · Updated Aug 3, 2024
Stored XSS in Cotonti Siena 0.9.20 allows remote authenticated users to execute script through a malicious forum poll. The forum topic workflow stores and later renders executable poll content without effective neutralization; the report does not identify the specific field or function. Administrator privileges are required to plant the payload, and another user must view the affected forum post; successful exploitation runs script in that viewer's browser context.
