CVE-2023-0693Network attack vector

Transaction ID disclosure via unchecked entry identifier

Published Jun 9, 2023 · Updated Apr 8, 2026

Information disclosure in Roxnor MetForm 3.3.1 and earlier allows remote authenticated users to read payment transaction IDs via a shortcode. The mf_transaction_id shortcode uses a request-supplied entry ID to read metform_entries__payment_trans metadata without binding the entry to the current user. Subscriber-level access and a payment-bearing form submission are required; arbitrary entry IDs expose transaction identifiers only.
