Rapid7 Velociraptor < 0.75.8 / 0.76.x < 0.76.3 Incorrect Authorization (CVE-2026-6290)

high Nessus Plugin ID 307355

Language:

Synopsis

An application installed on the remote host is affected by an incorrect authorization vulnerability.

Description

The version of Rapid7 Velociraptor installed on the remote host is prior to 0.75.8 or 0.76.x prior to 0.76.3. It is, therefore, affected by an incorrect authorization vulnerability:

 - Velociraptor contains a vulnerability in the query() plugin which allows access to all orgs with the user's current ACL token. This allows an authenticated GUI user with access in one org to use the query() plugin in a notebook cell to run VQL queries on other orgs which they may not have access to. The user's permissions in the other org are the same as the permissions they have in the org containing the notebook. (CVE-2026-6290)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Rapid7 Velociraptor version 0.75.8 / 0.76.3 or later.
