Summary
Budibase is an open-source low-code platform. Prior to 3.39.25, packages/server/src/api/controllers/automation.ts returned automation test results containing trigger.outputs.user.oauth2, broadcast BuilderSocketEvent.AutomationTestProgress to the app room, and stored progress in packages/server/src/automations/testProgress.ts without user scoping. A co-builder could receive or poll another SSO-authenticated builder test and obtain OAuth2 access and refresh tokens. The fix adds sanitizeAutomationTestResult and isolates progress by user. This issue is fixed in version 3.39.25.
Risk Assessment
The risk includes unauthorized access to other users' OAuth2 tokens, which can lead to account takeover and data confidentiality breach.
Recommendation
It is recommended to update Budibase to version 3.39.25 or later, which contains the fix.
Other vulnerabilities in Budibase
See all- CVE-2026-103757High
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.
- CVE-2026-48152High
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.
- CVE-2026-46427High
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.
- CVE-2026-46426High
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.
- CVE-2026-45717High
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.
- CVE-2026-45716High
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.
- CVE-2026-45548High
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.
- CVE-2026-82244Critical
Budibase versions before 3.41.3 contain a remote code execution vulnerability in plugin handling that allows authenticated admin users to execute arbitrary code by uploading a malicious plugin tarball. The server calls eval() on plugin JavaScript files without sandboxing in the main Node.js process, enabling attackers to exfiltrate environment variables and credentials with root privileges in default deployments.
- CVE-2026-73302Critical
Budibase prior to 3.39.30 has a vulnerability in the OIDC flow, where the email is not verified for email_verified, and accounts are linked based on email. An attacker who can authenticate through an identity provider with an unverified victim email can take over the victim's account and inherit their roles.
- CVE-2026-72851Critical
Budibase before 3.40.0 contains an unauthenticated SQL injection vulnerability in webhook-triggered automations with EXECUTE_QUERY steps. Attackers can POST attacker-controlled JSON to the webhook trigger endpoint to inject SQL payloads that execute with builder-configured database credentials, enabling data exfiltration, modification, and persistence in connected datasources.
