CWE-285  (opens in a new tab)

How to fix?

Upgrade @actual-app/sync-server to version 26.6.0 or higher.

Overview

@actual-app/sync-server is an actual syncing server

Affected versions of this package are vulnerable to Improper Authorization in the GET /secret/:name process. An attacker can determine the existence of admin-configured secrets by sending authenticated requests as a non-admin user and observing the response codes. This is only exploitable if the server is configured in OpenID multi-user mode and the attacker has a valid non-admin session.
