CVE-2026-54352

Budibase through 3.41.0 contains a server-side request forgery vulnerability in AI table generation because the uploadUrl function in packages/server/src/utilities/fileUtils.ts uses raw node-fetch instead of fetchWithBlacklist. Authenticated builder users can send a prompt to POST /api/ai/tables that places an internal URL in an attachment column, causing the server to fetch it and return a presigned object-storage URL containing the response, such as cloud metadata credentials.

Budibase server before 3.45.0 contains a cross-tenant information disclosure vulnerability in the GET /api/applications/:appId/appPackage endpoint that allows authenticated users to read another tenant's application metadata and source code. Attackers can supply a victim tenant's app id to retrieve sensitive application details including navigation structure, role names, internal screen URLs, JavaScript snippets, and user identifiers without authorization checks.

Budibase versions 3.41.0 before 3.45.0 contain an authentication bypass in the OIDC/SSO login path of @budibase/server. When no existing user matches the incoming SSO subject, the server looks up pending user invites by the IdP-asserted email address alone — without validating an invite code and without an email_verified check. An attacker who can register at an IdP that the tenant trusts for OIDC and assert a victim's invited email address claims the pending invite and inherits all of its granted privileges, including builder and admin.global.

Budibase versions before 3.45.0 fail to disable external JSON reference resolution in the OpenAPI/Swagger import validator, allowing authenticated builders to read arbitrary local files. Attackers with builder access can embed file:// references in OpenAPI specifications submitted to the import endpoint to exfiltrate sensitive files including environment variables containing JWT secrets, API keys, and database credentials.

Budibase is an open-source low-code platform that prior to version 3.39.0 had security vulnerabilities related to access to GET and PUT routes for single data sources. Basic role users could access sensitive information such as authorization secrets by manipulating configuration data.

Budibase is an open-source low-code platform that prior to version 3.38.3 did not properly mask sensitive data in the Snowflake integration. An authenticated BASIC user could retrieve the full PEM key in plaintext.

Budibase is an open-source low-code platform. Prior to version 3.38.2, the file upload endpoint POST /api/attachments/process does not enforce active-content restrictions for authenticated users, allowing authenticated builders to upload dangerous files.

Budibase prior to version 3.38.1 has a vulnerability in its REST API that allows authenticated app users to modify datasource configurations. Users with BASIC role or higher can send PUT requests to change settings, potentially leading to unauthorized access to sensitive data.

Budibase is an open-source low-code platform that prior to version 3.38.1 had a vulnerability in the POST /api/global/users/onboard endpoint. This allows builder-level users to create new global admin accounts, leading to privilege escalation.

Budibase is an open-source low-code platform. In versions prior to 3.34.8, the processUrlFile function in extract.ts did not validate IP addresses, allowing authenticated users to send requests to internal network addresses.
