SCA: security update for @budibase/server (GHSA-w7mq-r738-x278)

critical Tenable Self-Hosted Container Security Plugin ID 443792

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 3.39.9, `POST /api/pwa/process-zip` at
 packages/server/src/api/routes/static.ts:24 accepts a builder-uploaded .zip, extracts it with extract-
 [email protected] 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. [email protected] 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-2026-54352)

Solution

Update the @budibase/server library and its related packages to version 3.39.9 or later.
