CVE-2026-63664
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.

CVE-2026-63663
CloudBeaver is a cloud database manager. From version 23.2.3 until 26.1.2, a path traversal vulnerability in its SQL result-editing functionality allows an authenticated user with SQL result-editing privileges to cause the server to open files outside the intended temporary upload directory. In affected database value-handling scenarios, this can disclose local files readable by the CloudBeaver server process. Version 26.1.2 prevents traversal outside the intended temporary upload directory.
