Budibase: >> Budibase >> 3.23.31 Security Vulnerabilities
Budibase is an open-source low-code platform. Prior to version 3.33.4, an unauthenticated attacker can achieve Remote Code Execution (RCE) on the Budibase server by triggering an automation that contains a Bash step via the public webhook endpoint. No authentication is required to trigger the exploit. The process executes as root inside the container. This issue has been patched in version 3.33.4.

Budibase is an open-source low-code platform. Prior to version 3.32.5, Budibase's Builder Command Palette renders entity names (tables, views, queries, automations) using Svelte's {@html} directive without any sanitization. An authenticated user with Builder access can create a table, automation, view, or query whose name contains an HTML payload (e.g. <img src=x onerror=alert(document.domain)>). When any Builder-role user in the same workspace opens the Command Palette (Ctrl+K), the payload executes in their browser, stealing their session cookie and enabling full account takeover. This issue has been patched in version 3.32.5.

Budibase is an open-source low-code platform. Prior to version 3.33.4, a server-side request forgery (SSRF) vulnerability exists in Budibase's REST datasource connector. The platform's SSRF protection mechanism (IP blacklist) is rendered completely ineffective because the BLACKLIST_IPS environment variable is not set by default in any of the official deployment configurations. When this variable is empty, the blacklist function unconditionally returns false, allowing all requests through without restriction. This issue has been patched in version 3.33.4.

Budibase is an open-source low-code platform. Prior to version 3.33.4, the bash automation step executes user-provided commands using execSync without proper sanitization or validation. User input is processed through processStringSync which allows template interpolation, potentially allowing arbitrary command execution. This issue has been patched in version 3.33.4.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In versions from 3.30.6 and prior, the REST datasource query preview endpoint (POST /api/queries/preview) makes server-side HTTP requests to any URL supplied by the user in fields.path with no validation. An authenticated admin can reach internal services that are not exposed to the internet — including cloud metadata endpoints (AWS/GCP/Azure), internal databases, Kubernetes APIs, and other pods on the internal network. On GCP this leads to OAuth2 token theft with cloud-platform scope (full GCP access). On any deployment it enables full internal network enumeration. At time of publication, there are no publicly available patches.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.31.4 and earlier, the Budibase server's authorized() middleware that protects every server-side API endpoint can be completely bypassed by appending a webhook path pattern to the query string of any request. The isWebhookEndpoint() function uses an unanchored regex that tests against ctx.request.url, which in Koa includes the full URL with query parameters. When the regex matches, the authorized() middleware immediately calls return next(), skipping all authentication, authorization, role checks, and CSRF protection. This means a completely unauthenticated, remote attacker can access any server-side API endpoint by simply appending ?/webhooks/trigger (or any webhook pattern variant) to the URL.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.31.5 and earlier, a path traversal vulnerability in the PWA (Progressive Web App) ZIP processing endpoint (POST /api/pwa/process-zip) allows an authenticated user with builder privileges to read arbitrary files from the server filesystem, including /proc/1/environ which contains all environment variables — JWT secrets, database credentials, encryption keys, and API tokens. The server reads attacker-specified files via unsanitized path.join() with user-controlled input from icons.json inside the uploaded ZIP, then uploads the file contents to the object store (MinIO/S3) where they can be retrieved through signed URLs. This results in complete platform compromise as all cryptographic secrets and service credentials are exfiltrated in a single request.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. This issue is a combination of Vertical Privilege Escalation and IDOR (Insecure Direct Object Reference) due to missing server-side RBAC checks in the /api/global/users endpoints. A Creator-level user, who should have no permissions to manage users or organizational roles, can instead promote an App Viewer to Tenant Admin, demote a Tenant Admin to App Viewer, or modify the Owner’s account details and all orders (e.g., change name). This is because the API accepts these actions without validating the requesting role, a Creator can replay Owner-only requests using their own session tokens. This leads to full tenant compromise.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.24.0 and earlier, an arbitrary file upload vulnerability exists even though file extension restrictions are configured. The restriction is enforced only at the UI level. An attacker can bypass these restrictions and upload malicious files.

Budibase is a low code platform for creating internal tools, workflows, and admin panels. Prior to version 3.30.4, an unsafe `eval()` vulnerability in Budibase's view filtering implementation allows any authenticated user (including free tier accounts) to execute arbitrary JavaScript code on the server. This vulnerability ONLY affects Budibase Cloud (SaaS) - self-hosted deployments use native CouchDB views and are not vulnerable. The vulnerability exists in `packages/server/src/db/inMemoryView.ts` where user-controlled view map functions are directly evaluated without sanitization. The primary impact comes from what lives inside the pod's environment: the `app-service` pod runs with secrets baked into its environment variables, including `INTERNAL_API_KEY`, `JWT_SECRET`, CouchDB admin credentials, AWS keys, and more. Using the extracted CouchDB credentials, we verified direct database access, enumerated all tenant databases, and confirmed that user records (email addresses) are readable. Version 3.30.4 contains a patch.
