CVE-2026-50136 · Budibase: Unauthenticated S3 signed upload URL generation allows arbitrary writes with stored datasource credentials
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Budibase is an open-source low-code platform. Prior to 3.39.3, the application server exposes an unauthenticated endpoint that generates S3 PutObject presigned URLs using credentials stored in a workspace datasource. The route is protected only by the recaptcha middleware and does not require authentication, table permission, datasource permission, or builder access. A public caller who knows a workspace ID and S3 datasource ID can request a signed upload URL for attacker-controlled bucket and key values. This vulnerability is fixed in 3.39.3.
