Overview
@actual-app/sync-server is an actual syncing server
Affected versions of this package are vulnerable to Insufficient Session Expiration due to the lack of user status verification in the validateSession process. An attacker can maintain unauthorized access to server endpoints and sensitive data by reusing a valid session token after the associated user account has been disabled. This is only exploitable if the session token has not expired, which is the default configuration where token expiration is set to 'never'.
