NVD description

Budibase is an open-source low-code platform. Prior to 3.39.0, the OAuth2 token fetch function in packages/server/src/sdk/workspace/oauth2/utils.ts uses raw fetch(config.url) with no SSRF protection. The safe wrapper fetchWithBlacklist() exists in the same codebase and is used in every other outbound HTTP call (automation steps, plugin downloads, object store), but was not applied to the OAuth2 token endpoint. A user with BUILDER role can point the OAuth2 token URL to internal services (CouchDB, cloud metadata) to exfiltrate sensitive data. This vulnerability is fixed in 3.39.0.
