Upgrade @nocobase/auth to version 1.9.0-beta.18, 1.9.22, 2.0.0-alpha.52 or higher.
Overview
@nocobase/auth is a
Affected versions of this package are vulnerable to Improper Protection for Out of Bounds Signal Level Alerts via the official one-click Docker deployment configuration, a public default JWT key was historically provided.. An attacker can gain unauthorized access to administrative functions and sensitive data by forging valid authentication tokens using a known default secret.
Note: This is only exploitable if the deployment uses the default Docker configuration without explicitly overriding the JWT secret.
Workaround
This vulnerability can be mitigated by explicitly setting a strong, randomly generated JWT secret via environment variables, restarting all running instances, invalidating all existing JWT sessions, and ensuring no default secret values are present in configuration files or secrets.
