@budibase/backend-core has potential SSRF DNS rebinding bypass in outbound fetch validation (CVE-2026-54353)CVE-2026-54353 0 Authenticated users with automation permissions in Budibase backend-core versions prior to 3.39.9 can exploit a Server-Side Request Forgery (SSRF) vulnerability via DNS rebinding. The vulnerability arises because the hostname validation and the actual DNS resolution for outbound fetch requests are performed separately, allowing an attacker-controlled hostname to resolve to a public IP during validation and a private/internal IP during the actual connection. This enables non-blind SSRF attacks against internal services including loopback, RFC1918 ranges, and cloud metadata endpoints. The vulnerability affects multiple automation steps that perform outbound fetches, potentially exposing sensitive internal resources and cloud credentials.
