Detailsinfo

A vulnerability, which was classified as critical, was found in budibase up to 3.35.2. Affected is an unknown function of the component VectorDB Configuration Endpoint. The manipulation of the argument host with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918.
