Description
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.

AI Analysis

Impact

A server-side request forgery flaw exists in Budibase when generating AI tables (CWE-918). The uploadUrl function uses raw node-fetch instead of a blacklisted wrapper, allowing a builder to embed an internal URL within an attachment column. When the server follows that URL, it retrieves the response and returns a presigned object-storage URL that contains the original content, which may include sensitive data such as cloud metadata credentials. This can lead to disclosure of internal information but does not grant remote code execution.

Affected Systems

Budibase versions prior to 3.41.0 are affected. Users of Budibase who rely on AI table generation functionality should confirm they are running a version older than 3.41.0 or have not applied the containing patch.

Risk and Exploitability

The vulnerability has a CVSS score of 8.3, indicating high severity. EPSS data is not available and the issue is not listed in the CISA KEV catalog. The likely attack vector is via authenticated builder users; they can send a crafted POST request to /api/ai/tables with a prompt that points to an internal URL, causing the backend to fetch it and expose the retrieved data. No additional attack prerequisites are stated in the description, so having builder level access is the primary condition for exploitation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Budibase release (3.41.0 or newer) which removes the unfiltered fetch usage.
  • Restrict or temporarily disable AI table generation for builder accounts until the patch is applied.
  • Monitor backend requests and logs for unexpected outbound traffic to detect possible exploitation attempts.
