OAuth connection data disclosure via unchecked AJAX handler
Published Apr 5, 2021 · Updated Aug 3, 2024
Information disclosure in Saturday Drive Ninja Forms before 3.4.34.1 allows remote authenticated users to retrieve OAuth connection data. The wp_ajax_nf_oauth AJAX handler returns a connection URL containing the client secret and an existing client_id without checking caller capability. Subscriber-level access exposes the connection material; completing an attacker-controlled Add-on Manager connection also requires an administrator to follow a crafted link.
