Description
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.

AI Analysis

Impact

A function used in the AI Extract File automation step fetches URLs without enforcing the IP blacklist that applies to other steps, enabling SSRF. An authenticated user can trigger server‑side requests to arbitrary internal addresses, potentially exposing sensitive data or assisting lateral movement. The weakness corresponds to CWE‑918.

Affected Systems

Budibase, an open‑source low‑code platform, is affected in all releases prior to version 3.34.8; the vulnerability exists in the processUrlFile function located in packages/server/src/automations/steps/ai/extract.ts.

Risk and Exploitability

The CVSS score is 7.7, indicating a high severity. EPSS is not available and the issue is not listed in CISA KEV. Exploitation requires an authenticated user who can create or run the AI Extract File automation step. Through this vector, an attacker could target internal resources and gather information or further compromise the network.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Budibase to version 3.34.8 or later, which includes the IP blacklist validation for the AI Extract File step.
  • Restrict access to the AI Extract File automation step so that only trusted users can trigger it.
  • If upgrading immediately is not possible, enforce strict IP restrictions on outbound requests from the server to block internal addresses.
