Credential disclosure via unvalidated datasource URLs
Published Aug 28, 2026 · Updated Aug 28, 2026
SSRF in Budibase Server before 3.41.3 allows remote authenticated users with builder access to disclose CouchDB credentials. The datasource connector accepts an arbitrary URL without blacklist validation, then getCouchInfo falls back to internal CouchDB credentials and buildNano sends them in a Basic Authorization header. Builder access is required; successful exploitation exposes database credentials and can grant access to application and user data in cloud deployments.
