What an attacker can do
The source says when the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Vendor/CNA’s CVSS 4.0 assessment (base score 7.1/10) rates confidentiality impact as high; integrity impact as low; availability impact as none.
