Technical details

The vulnerability exists in Directus's WebSocket authentication handler for public-mode connections. When an attacker sends an invalid authentication token, the handleAuthRequest function sets accountability to null instead of rejecting the connection, allowing subsequent operations to skip permission checks. This affects all user-defined collections accessible via the public WebSocket interface.

Affected products

Directus Directus before 12.1.0
