CVE-2026-67311 Details
Description
Budibase before 3.38.1 contains a server-side request forgery vulnerability in the REST datasource integration that fails to validate HTTP redirects against the IP blacklist. Attackers with Builder role can configure a REST datasource pointing to an external server that returns a redirect to internal IP addresses, bypassing blacklist protection to access cloud metadata endpoints and internal services.
A server-side request forgery (SSRF) vulnerability has been identified in Budibase versions prior to 3.38.1. This vulnerability exists in the REST datasource integration, which fails to properly validate HTTP redirects against an IP blacklist. As a result, attackers with a Builder role can create a REST datasource that points to an external server. If this server returns a redirect to an internal IP address, the blacklist protection can be bypassed, allowing access to cloud metadata endpoints and internal services.
Users are advised to update Budibase to version 3.38.1 or later, where this vulnerability has been patched.
