UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

Budibase is an open-source low-code platform. Prior to 3.40.1, packages/server/src/integrations/mongodb.ts passed builder-controlled tlsCertificateKeyFile and tlsCAFile values directly to MongoClient on Budibase Cloud. A builder could submit absolute server paths through /api/datasources/verify and distinguish readable existing files from missing files by comparing the driver error, exposing a filesystem existence and readability oracle on the shared server. This issue is fixed in version 3.40.1.
