CVE-2025-57393Public exploitNetwork attack vector

Administrative session compromise via unsanitized form fields

Published Oct 1, 2025 · Updated Jul 5, 2026

Stored XSS in Kissflow Work Platform before 7337 allows remote attackers to execute scripts when an administrator reviews a crafted form. The web form rendering engine stores user-submitted field values without adequate sanitization or output encoding and inserts them into the administrative review interface. Exploitation requires an administrator or reviewer to open the submission, allowing the script to access browser-session data and perform actions in that user's context.
