Description

CloudBeaver is a cloud database manager. In versions up to and including 26.1.1, some server-side export operations do not consistently enforce the global data export restriction. An authenticated non-administrative user with access to a shared database connection can initiate certain server-side data exports even when an administrator has disabled exports. This can disclose database contents that the user is permitted to query but is not permitted to export. The issue does not grant additional database read privileges. It is fixed in 26.1.2 by consistently enforcing the global restriction for server-side exports.
