Budibase: Server-Side Request Forgery via REST Connector with Empty Default Blacklist
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, GHSA.
Beschreibung
Budibase is an open-source low-code platform. Prior to version 3.33.4, a server-side request forgery (SSRF) vulnerability exists in Budibase's REST datasource connector. The platform's SSRF protection mechanism (IP blacklist) is rendered completely ineffective because the BLACKLIST_IPS environment variable is not set by default in any of the official deployment configurations. When this variable is empty, the blacklist function unconditionally returns false, allowing all requests through without restriction. This issue has been patched in version 3.33.4.
