Budibase Budibase vulnerabilities

CVE-2026-103757 High · 7.7 CWE-918 Oct 1, 2026

Budibase before 3.41.0 SSRF via uploadUrl in AI Table Generation

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-2026-73410 High · 8.5 CWE-367 Aug 17, 2026

Budibase: SSRF via DNS rebinding in the REST datasource integration

Budibase is an open-source low-code platform. Prior to 3.40.0, packages/backend-core/src/utils/outboundFetch.ts pinned a validated address through a Node agent, but the REST integration used getDispatcher from packages/backend-core/src/utils/fetch.ts, causing undici to ignore that agent and resolve the hostname again. A builder could use DNS rebinding to make packages/server/src/integrations/rest.ts connect to an internal address after a public address passed validation, with full response access and arbitrary REST methods. The fix adds createPinnedLookup support to the undici dispatcher and passes the validated address to custom fetch implementations. This issue is fixed in version 3.40.0.

CVE-2026-64657 High · 8.4 CWE-89 Aug 17, 2026

Budibase: Database Connector SQL Injections in PostgreSQL, MS SQL, and MySQL

Budibase is an open-source low-code platform. Prior to 3.39.19, the PostgreSQL datasource connector in packages/server/src/integrations/postgres.ts interpolates the user-controlled schema configuration field into a SET search_path statement without escaping embedded double quotes, allowing an authenticated administrator who saves or tests the datasource to execute arbitrary SQL through the simple query protocol. This issue is fixed in version 3.39.19.

CVE-2026-54356 High · 7.1 CWE-862 Aug 17, 2026

Budibase authenticated arbitrary S3 signed upload URL issuance via `/api/attachments/:datasourceId/url`

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.

CVE-2026-35219 High · 7.1 CWE-918 Aug 17, 2026

Budibase: SSRF in Automation Steps - Webhook, Zapier, N8N, Slack, Discord Bypass IP Blacklist

Budibase is an open-source low-code platform. Prior to 3.41.3, automation steps in packages/server/src/automations/steps/outgoingWebhook.ts, packages/server/src/automations/steps/zapier.ts, packages/server/src/automations/steps/n8n.ts, packages/server/src/automations/steps/slack.ts, and packages/server/src/automations/steps/discord.ts use node-fetch on user-provided URLs without the BLACKLIST_IPS enforcement used by the REST integration, allowing an authenticated user to make server-side requests to cloud metadata and internal services. This issue is fixed in version 3.41.3.

CVE-2026-73408 High · 7.6 CWE-89 Aug 13, 2026

Budibase: MySQL DESCRIBE Backtick Injection via multipleStatements in Database Connector

Budibase is an open-source low-code platform. Prior to 3.39.18, packages/server/src/integrations/mysql.ts enabled multipleStatements and inserted an unescaped tableName into a DESCRIBE statement. An attacker able to create a MySQL table with a backtick and stacked statement in its name could wait for a Budibase administrator to run schema discovery, causing the second statement to execute. The fix applies quoteMySqlIdentifier before constructing the query. This issue is fixed in version 3.39.18.

CVE-2026-73305 High · 8.8 CWE-269 Aug 13, 2026

Budibase: Privilege escalation via public role assignment API missing app-level authorization

Budibase is an open-source low-code platform. Prior to 3.39.24, POST /api/public/v1/roles/assign called validateGlobalRoleUpdate without checking appBuilder.appId or role.appId in packages/server/src/api/controllers/public/globalRoleValidation.ts. An app-scoped builder could scope the request to an app they control and then grant themselves builder access or an arbitrary role in another app, exposing that app data, datasource configuration, and automations. This issue is fixed in version 3.39.24.

CVE-2026-73304 Medium · 4.9 CWE-200 Aug 13, 2026

Budibase: SSO OAuth2 Token Leakage via User Metadata Endpoints to Power-Role Users

Budibase is an open-source low-code platform. Prior to 3.39.25, GET /api/users/metadata and GET /api/users/metadata/:id returned user objects processed by packages/server/src/utilities/global.ts without removing oauth2.accessToken or oauth2.refreshToken. A user with the POWER role could retrieve the identity-provider credentials of SSO-authenticated users and use the refresh tokens for persistent access to connected services. This issue is fixed in version 3.39.25.

CVE-2026-73302 Critical · 9.0 CWE-287 Aug 13, 2026

Budibase: OIDC SSO account takeover: incoming identity linked by email without checking email_verified

Budibase is an open-source low-code platform. Prior to 3.39.30, the OIDC flow in packages/backend-core/src/middleware/passport/sso/oidc.ts resolved an email without getEmailVerified or an email_verified requirement, and packages/backend-core/src/middleware/passport/sso/sso.ts then used users.getGlobalUserByEmail as a fallback account-linking key. An attacker who can authenticate through a configured identity provider that asserts a victim email as unverified can have a fresh provider identity merged into the victim Budibase account and inherit the victim roles. This issue is fixed in version 3.39.30.

CVE-2026-72857 High · 7.7 CWE-522 Aug 13, 2026

Budibase before 3.40.0 Credential Exposure via STRING Fields

Budibase before 3.40.0 fails to redact datasource credentials stored in STRING typed fields, allowing authenticated users to read MongoDB connection strings and Firebase private keys in plaintext. Attackers with table read permissions can retrieve datasource configurations through the read API to obtain live backend database credentials and service account keys.

CVE-2026-72856 High · 8.1 CWE-640 Aug 13, 2026

Budibase before 3.40.0 Authentication Bypass via Tenant Owner Email

Budibase versions before 3.40.0 contain an authorization/authentication bypass in the PUT /api/global/users/tenant/owner (changeTenantOwnerEmail) endpoint. On self-hosted instances (SELF_HOSTED or DISABLE_ACCOUNT_PORTAL set), the cloudRestricted middleware is a no-op and the route is protected only by a general authentication check, so any authenticated user — including a lowest-privilege BASIC app user — can reassign the tenant account-holder (top-privilege admin) email to an attacker-controlled address. The attacker can then use the public password-reset flow to take over the admin account, leading to full administrative access.

CVE-2026-72853 High · 7.6 CWE-89 Aug 13, 2026

Budibase before 3.40.0 SQL Injection via Oracle connector

Budibase before 3.40.0 contains a SQL injection vulnerability in the Oracle datasource connector's post-write row lookup that fails to escape table names in identifiers. Attackers with write permission on a table with a double-quote in its name can inject SQL that executes as the datasource's database user to read or modify arbitrary data.

CVE-2026-73409 Medium · 5.1 CWE-203 Aug 12, 2026

Budibase: Server Filesystem Existence/Read Oracle via Builder-Controlled MongoDB tlsCertificateKeyFile

Budibase is an open-source low-code platform. Prior to 3.40.1, packages/server/src/integrations/mongodb.ts passed builder-controlled tlsCertificateKeyFile and tlsCAFile values directly to MongoClient on Budibase Cloud. A builder could submit absolute server paths through /api/datasources/verify and distinguish readable existing files from missing files by comparing the driver error, exposing a filesystem existence and readability oracle on the shared server. This issue is fixed in version 3.40.1.

CVE-2026-73407 Critical · 9.0 CWE-22 Aug 12, 2026

Budibase: Unauthenticated REST Datasource Credential Theft via Cross-Origin Auth Leak (bypass of CVE-2026-48152))

Budibase is an open-source low-code platform. Prior to 3.40.1, RestIntegration._req in packages/server/src/integrations/rest.ts attached credentials from getAuthHeaders and defaultHeaders without requiring the final request destination to match the datasource origin. An unauthenticated caller of a PUBLIC POST /api/v2/queries/:queryId query could supply an absolute or parameterized path to an attacker-controlled host and receive the stored bearer, basic, or static-header credentials. This issue is fixed in version 3.40.1.

CVE-2026-73406 High · 7.5 CWE-200 Aug 12, 2026

Budibase: Unauthenticated user information disclosure via public tenant user lookup endpoint

Budibase is an open-source low-code platform. Prior to 3.39.32, GET /api/global/users/tenant/:id was listed in PUBLIC_ENDPOINTS in packages/worker/src/api/index.ts, and tenantUserLookup returned a full PlatformUser document. An unauthenticated caller could query an email or user identifier, distinguish existing users from missing users, and obtain tenant identifiers, user identifiers, email addresses, SSO identifiers, and document revision metadata. This issue is fixed in version 3.39.32.

CVE-2026-73308 Medium · 5.7 CWE-200 Aug 12, 2026

Budibase: OAuth2 Token Disclosure via Automation Test Results Broadcast to Other Builders

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.

CVE-2026-73307 Medium · 4.9 CWE-918 Aug 12, 2026

Budibase: SSRF via bare fetch() in uploadUrl during AI table generation

Budibase is an open-source low-code platform. Prior to 3.39.4, uploadUrl in packages/server/src/utilities/fileUtils.ts used a bare server-side fetch for string attachment values passed by processAttachments in packages/server/src/sdk/workspace/ai/helpers/rows.ts. A builder with the AI table-generation feature could cause an attachment value to reference an internal service or cloud metadata endpoint, and the response would be stored as an attachment without fetchWithBlacklist validation. This issue is fixed in version 3.39.4.

CVE-2026-73306 Medium · 5.3 CWE-204 Aug 12, 2026

Budibase: Account Enumeration via Login Lockout Response Differential

Budibase is an open-source low-code platform. Prior to 3.39.25, POST /api/global/auth/:tenantId/login incremented the failure counter in packages/worker/src/api/controllers/global/auth.ts only for existing users, while packages/worker/src/middleware/emailLockout.ts returned X-Account-Locked and Retry-After only for locked identifiers. An unauthenticated attacker could compare the response after repeated failures to enumerate valid email addresses and temporarily lock valid accounts. This issue is fixed in version 3.39.25.

CVE-2026-73303 High · 8.2 CWE-639 Aug 12, 2026

Budibase: Email Change IDOR via POST /api/v2/email allows full Account Takeover (accountId not validated against session)

Budibase is an open-source low-code platform. Prior to 3.40.0, POST /api/v2/email on account.budibase.app accepted a client-controlled accountId without binding it to the authenticated session, while checking only currentEmail. An authenticated attacker who obtains a victim account identifier can start the email-change workflow for the victim, receive and submit the verification code through POST /api/v2/email/verification, move the victim email to an attacker-controlled address, and complete a password reset as the victim. This issue is fixed in version 3.40.0.

CVE-2026-73301 Medium · 4.3 CWE-862 Aug 12, 2026

Budibase: Missing RBAC on GET /api/global/groups allows BASIC users to enumerate all tenant groups and role mappings

Budibase is an open-source low-code platform. Prior to 3.39.25, the GET /api/global/groups endpoint in packages/worker/src/api/routes/global/groups.ts omitted auth.builderOrAdmin, allowing an authenticated BASIC role user to enumerate tenant groups, role mappings and user memberships, builder permissions, and default-group flags. The disclosure exposes the tenant access-control structure to users who are not builders or administrators. This issue is fixed in version 3.39.25.

CVE-2026-73300 Critical · 9.6 CWE-89 Aug 12, 2026

Budibase: SQL Injection via `multipleStatements: true`

Budibase is an open-source low-code platform. Prior to 3.40.0, the MySQL integration component in Budibase is configured with multipleStatements: true, enabling execution of multiple SQL statements in a single query. Attackers can inject malicious SQL commands through user input fields, leading to complete database compromise. This vulnerability is fixed in 3.40.0.

CVE-2026-67311 Medium · 6.8 CWE-918 Aug 1, 2026

Budibase before 3.38.1 SSRF Blacklist Bypass via HTTP Redirect

Budibase before 3.38.1 contains a server-side request forgery vulnerability in the REST datasource integration that fails to validate HTTP redirects against the IP blacklist. Attackers with Builder role can configure a REST datasource pointing to an external server that returns a redirect to internal IP addresses, bypassing blacklist protection to access cloud metadata endpoints and internal services.

CVE-2026-54353 High · 7.1 CWE-367 Jun 26, 2026

Budibase: Potential SSRF DNS rebinding bypass in outbound fetch validation

Budibase is an open-source low-code platform. Prior to 3.39.9, authenticated users with automation permissions can bypass Budibase's SSRF blacklist through DNS rebinding. The outbound fetch flow validates a hostname against the blacklist before the request is sent, but the actual socket connection later performs a separate DNS lookup through node-fetch. Since the validated IPs are never pinned to the connection, an attacker-controlled hostname can return a public IP during validation and a private/internal IP during the real connection. This results in a non-blind SSRF primitive against internal services reachable from the Budibase host, including loopback, RFC1918 ranges, and cloud metadata endpoints. This vulnerability is fixed in 3.39.9.

CVE-2026-54352 Critical · 9.6 CWE-22 Jun 26, 2026

Budibase Path Traversal via Symlinks in PWA Icon Upload

Budibase is an open-source low-code platform. Prior to 3.39.9, `POST /api/pwa/process-zip` at packages/server/src/api/routes/static.ts:24 accepts a builder-uploaded .zip, extracts it with extract-zip@2.0.1 into a temp directory, then for each entry listed in icons.json validates the icon path, opens it, and streams the bytes into MinIO. The resulting object is served back via GET /api/assets/{appId}/pwa/{uuid}.png. extract-zip@2.0.1 preserves absolute symlink targets when restoring symlink entries. The icon-source validator at packages/server/src/api/controllers/static/index.ts:259-268 resolves the icon source string against baseDir (path.resolve), checks resolvedSrc.startsWith(baseDir + path.sep) against that string, and calls fs.existsSync(resolvedSrc) which follows symbolic links to confirm the target exists. None of the three calls reject symbolic-link entries. packages/backend-core/src/objectStore/objectStore.ts:302 then calls (await fsp.open(path)).createReadStream() on the resolved path. fsp.open follows the symlink, the target file's bytes stream into MinIO, and the response of the asset-fetch endpoint returns those bytes verbatim. Result: a workspace-level builder reads any file the server process can open. This vulnerability is fixed in 3.39.9.

CVE-2026-54351 Critical · 9.6 CWE-915 Jun 26, 2026

Budibase Mass Assignment in Webhook Trigger Enabling Cross-Workspace Automation Execution

Budibase is an open-source low-code platform. Prior to 3.39.9, the webhook trigger endpoint in Budibase is publicly accessible and passes the full HTTP request body into automation execution parameters. A mass assignment vulnerability in externalTrigger() allows an attacker to overwrite the internal appId property by including it in the webhook POST body. When the automation is processed asynchronously (the default path for webhooks without a collect step), the worker executes the attacker-defined automation in the context of the victim's workspace, granting full read/write access to the victim's database. This vulnerability is fixed in 3.39.9.
