OpenReplay is a self-hosted session replay suite. From 1.24.0 before 1.25.0, the OpenReplay tracking SDK accepts custom event names and captured page URLs from any visitor using a public project key, stores them in ClickHouse without output encoding, and later renders them in the authenticated dashboard through TextEllipsis and the event-details modal, allowing an unauthenticated attacker to store script that executes in the dashboard origin, reads the session JWT from localStorage, and takes over a dashboard account. This issue is fixed in version 1.25.0.
