Administrator takeover via unsanitized table cells
Published Mar 9, 2026 · Updated Mar 9, 2026
Stored XSS in Appsmith before 1.96 allows remote authenticated users to take over an administrator account through a malicious table. TableWidgetV2's BasicCell component returns unsanitized URL or plain-text cell values as React children, allowing injected HTML attributes to execute in the DOM. Exploitation requires an administrator to open an invited application; the script can read the XSRF token and call /api/v1/admin/env in that session.
