Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2026-48150

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, /api/public/v1/roles/assign is guarded by the builderOrAdmin middleware, which passes any user who is a builder for the app id in the x-budibase-app-id header. That check admits both global builders and workspace-scoped builders (builder.apps set but builder.global unset). The controller then spreads the request body into the SDK call, and the SDK grants builder.global=true or admin.global=true on whichever user ids the caller supplies. Bob, a workspace-scoped builder with an API key, promotes himself or any other user to global admin with one POST. The whole flow is tenant-wide privilege escalation from an app-level role, available to anyone with an Enterprise license that unlocks the EXPANDED_PUBLIC_API feature. This vulnerability is fixed in 3.39.0.

CVE-2026-48153

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, fetchToken in the OAuth2 SDK makes a POST to a builder-supplied URL with plain node-fetch, skipping the blacklist.isBlacklisted check that every other outbound fetch path in the codebase uses. The Joi schema for the OAuth2 URL has no scheme or host restriction. This vulnerability is fixed in 3.39.0.

CVE-2026-48147

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.35.4, the buildMatcherRegex() / matches() functions in packages/backend-core/src/middleware/matchers.ts route patterns are compiled into unanchored regular expressions and tested against ctx.request.url, which includes the full query string. The CSRF middleware in the Budibase Worker uses this matching system to decide whether to skip CSRF token validation. An unauthenticated attacker can forge state-changing cross-origin requests against any Worker API endpoint by injecting a public route pattern into the query string, causing the CSRF middleware to skip token validation entirely. This allows actions such as sending admin invites, modifying global configuration, and managing users without a valid CSRF token. This vulnerability is fixed in 3.35.4.

CVE-2026-48152

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, the single-datasource GET and PUT routes are guarded by generic TABLE READ, not by Builder/Admin permission or datasource-specific ownership/resource checks. The built-in Basic app user role maps to the WRITE permission set, which includes table read/write and query write. A Basic user can therefore read an existing REST datasource, receive redacted authConfigs values, submit an update that changes only config.url while keeping the redacted placeholders, and trigger an existing saved relative-path REST query. During update, mergeConfigs() restores the old stored secret when it sees the redaction placeholder. During query execution, Budibase prefixes the attacker-controlled datasource config.url to the relative query path and applies the resolved stored auth headers. The result is server-side disclosure of the builder-configured REST Authorization secret to an attacker-controlled listener. This vulnerability is fixed in 3.39.0.

CVE-2026-48149

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, the Budibase Text component renders markdown by assigning marked.parse(markdown) straight to innerHTML with no sanitizer (packages/bbui/src/Markdown/MarkdownViewer.svelte:22). Any column a builder binds to a Text component in Markdown mode is a stored-XSS sink writable by every BASIC app user with WRITE on the underlying table. This vulnerability is fixed in 3.39.0.

CVE-2026-48151

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, the webhook schema-building endpoint is registered under builderRoutes, but the generic authorization middleware skips authorization for all paths matching /api/webhooks/schema. As a result, an unauthenticated caller can update the body schema for a known webhook and mutate the corresponding automation trigger output schema. This vulnerability is fixed in 3.39.0.

CVE-2026-46426

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.38.2, the file upload endpoint POST /api/attachments/process does not enforce active-content restrictions for authenticated users. The checks for dangerous file extensions are conditionally wrapped inside if (isPublicUser) or if (isPublicUser || !env.SELF_HOSTED), meaning any authenticated builder can upload executable web content — SVG files with inline tags, HTML pages with JavaScript, .js modules — which are then stored in the object store (MinIO/S3) with their correct MIME types. When the resulting signed URL is opened by any app user, the browser executes the payload. Impact is persistent stored XSS over all application end users. This vulnerability is fixed in 3.38.2.

CVE-2026-45719

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.38.1, the V1 Views API (POST /api/views) accepts a calculation parameter from the request body that is interpolated directly into a CouchDB reduce function definition without validation. Although an internal SCHEMA_MAP object defines the valid calculation types (sum, count, stats), no actual validation is performed against this map before the value is used in string interpolation. A user with Builder permissions can inject arbitrary JavaScript code that will be executed within the CouchDB JavaScript engine when the view is queried. This vulnerability is fixed in 3.38.1.

CVE-2026-48128

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, the executeQuery automation step in Budibase accepts a queryId from automation step inputs and passes it directly to the query execution controller without additional validation. When combined with a REST datasource configured to target internal infrastructure, this creates a server-side request forgery path where automation execution causes the Budibase server to make outbound HTTP requests to attacker-influenced destinations. The automation output then returns the response, potentially exposing internal service data. This vulnerability is fixed in 3.39.0.

CVE-2026-46424

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.38.2, the public API role unassignment endpoint (POST /api/public/v1/roles/unassign) updates user documents in CouchDB but does not invalidate the corresponding Redis user cache entries. Because the authentication middleware resolves user identity and permissions from this cache (TTL: 3600 seconds), a user whose admin, builder, or app-level roles have been revoked via the public API retains those privileges for up to 1 hour. This vulnerability is fixed in 3.38.2.

CVE-2026-46427

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.38.3, removeSecrets at packages/server/src/sdk/workspace/datasources/datasources.ts masks only datasource config fields whose schema type is DatasourceFieldType.PASSWORD. The Snowflake integration types its privateKey field as SENSITIVE_LONGFORM, which the filter skips. GET /api/datasources/:datasourceId lives on authorizedRoutes guarded by PermissionType.TABLE + PermissionLevel.READ. An authenticated BASIC user with any app role and call the endpoint and receive the full Snowflake PEM in plaintext. This vulnerability is fixed in 3.38.3.

CVE-2026-48146

Publication date:

27/05/2026

Budibase is an open-source low-code platform. Prior to 3.39.0, the OAuth2 token fetch function in packages/server/src/sdk/workspace/oauth2/utils.ts uses raw fetch(config.url) with no SSRF protection. The safe wrapper fetchWithBlacklist() exists in the same codebase and is used in every other outbound HTTP call (automation steps, plugin downloads, object store), but was not applied to the OAuth2 token endpoint. A user with BUILDER role can point the OAuth2 token URL to internal services (CouchDB, cloud metadata) to exfiltrate sensitive data. This vulnerability is fixed in 3.39.0.
