Description

Parse Dashboard is a standalone dashboard for managing Parse Server apps. In versions 7.3.0-alpha.42 through 9.0.0-alpha.7, the AI Agent API endpoint (POST /apps/:appId/agent) lacks CSRF protection. An attacker can craft a malicious page that, when visited by an authenticated dashboard user, submits requests to the agent endpoint using the victim's session. The fix in version 9.0.0-alpha.8 adds CSRF middleware to the agent endpoint and embeds a CSRF token in the dashboard page. As a workaround, remove the agent configuration block from your dashboard configuration. Dashboards without an agent config are not affected.
