Published · Updated · NVD status: Deferred
What it is
An action never checks whether the caller is allowed to perform it.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker reach data or actions their role should not allow.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade dbeaver cloudbeaver to 26.1.2 or later.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
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.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
- Multi-tenant services. The flaw sits between one role or tenant and another.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
Questions to answer about your own systems
- Where does dbeaver cloudbeaver run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
