Budibase Server before 3.41.3 contains a server-side request forgery vulnerability in the datasource verify endpoint that allows builder-level users to supply arbitrary URLs without SSRF validation. Attackers can exploit this to leak internal CouchDB credentials by making requests to attacker-controlled servers, gaining full database access in cloud deployments.
AnalysisAI
Server-side request forgery in Budibase Server before 3.41.3 allows authenticated builder-level users to supply arbitrary URLs to the datasource verify endpoint without SSRF validation, causing the server to make outbound requests to attacker-controlled infrastructure. The primary impact is credential leakage: internal CouchDB connection credentials are exposed in those outbound requests, granting an attacker direct, full administrative access to the backend database. …
