SCA: security update for @budibase/server (GHSA-8qv3-p479-cj62)

critical Tenable Cloud Security Plugin ID 443816

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Budibase is an open-source low-code platform. Prior to 3.39.12, an unauthenticated visitor of any
 published Budibase app reads every document of the backing MongoDB, CouchDB, Elasticsearch, DynamoDB-
 PartiQL, or REST-with-JSON-body collection and, where the builder has published a PUBLIC write query,
 modifies every document of that collection with one HTTP request. enrichContext at
 packages/server/src/sdk/workspace/queries/queries.ts:121-138 substitutes parameter values into the raw
 JSON body of a query, then JSON.parses the result. The validator validateQueryInputs at
 packages/server/src/api/controllers/query/index.ts:61-71 rejects only Handlebars markers ({{, }}) in user
 input and does not escape JSON metacharacters (", \, }). A parameter value containing a closing quote and
 additional keys lifts attacker-controlled fields into the parsed filter object. For Mongo find, the parsed
 filter passes directly to collection.find() (packages/server/src/integrations/mongodb.ts:506-510).
 Duplicate-key JSON parsing overrides the builder's {name: "..."} with {name: {$exists: true}} and returns
 every document. The same primitive against an updateMany query (mongodb.ts:577-585) widens the filter
 scope to the full collection while the builder-controlled $set body runs against every matched document.
 The authorized middleware at packages/server/src/middleware/authorized.ts:141-148 short-circuits when the
 query's role is PUBLIC. CSRF is not enforced on this path. POST /api/v2/queries/:queryId
 (packages/server/src/api/routes/query.ts:63) accepts the call with no session, only an x-budibase-app-id
 header that is public from the published-app URL. This vulnerability is fixed in 3.39.12. (CVE-2026-54350)

Solution

Update the @budibase/server library and its related packages to version 3.39.12 or later.
