Budibase is an open-source low-code platform. Prior to 3.41.3, POST /api/attachments/:datasourceId/url in packages/server/src/api/routes/static.ts and packages/server/src/api/controllers/static/index.ts allows an authenticated published-app user with the BASIC role to supply attacker-controlled bucket and key values and obtain signedUrl and publicUrl values backed by stored S3 datasource credentials. This issue is fixed in version 3.41.3.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
