Description
The Pixelavo WordPress plugin before 1.5.4 registers an unauthenticated AJAX action, gated only by a nonce that it emits publicly on every front-end page, that forwards client-supplied event data to the configured Facebook Conversions API using the administrator-s stored access token. This allows an unauthenticated visitor to inject arbitrary conversion events into the administrator-s Facebook ads account and exhaust the configured API quota.
