CVE-2023-43191Network attack vector

Cookie theft via stored comment script injection

Published Sep 27, 2023 · Updated Sep 24, 2024

Stored cross-site scripting in SpringbootCMS 1.0 allows remote authenticated users to execute JavaScript when users view a crafted comment. The foreground-message path stores attacker-supplied HTML in the database and later renders it in comments without neutralizing executable markup. A valid account is required to plant the payload, and a reader must open the affected comment before the script can access browser data such as cookies.
