Detailsinfo

A vulnerability was found in budibase up to 3.34.7. It has been rated as critical. Affected by this issue is the function processUrlFile of the file packages/server/src/automations/steps/ai/extract.ts. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Budibase is an open-source low-code platform. Prior to 3.34.8, the processUrlFile function in packages/server/src/automations/steps/ai/extract.ts uses fetch(fileUrl) directly without the IP blacklist validation that is consistently applied to all other automation steps. This allows an authenticated user to trigger server-side requests to internal network addresses. This vulnerability is fixed in 3.34.8.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-45548 since 05/12/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit.
