ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

Chartbrew is an open-source web application for creating charts from databases and APIs. In versions 4.8.5 through 5.2.2, API connection creation and update operations accept the internal allowPrivateHost field from user input. An authenticated user with permission to manage API connections can enable this field to bypass private and reserved-network destination restrictions. An upgrade migration also enables the override on pre-existing API connections. The per-connection setting takes precedence over CB_ALLOW_PRIVATE_NETWORK_CALLS , so disabling that instance option does not protect connections with the override enabled. Successful exploitation allows requests to internal HTTP services reachable from the Chartbrew server, potentially disclosing information or triggering unauthorized actions depending on the target service. Recognized cloud metadata endpoints remain separately blocked. This issue is fixed in version 5.2.3.
