Unauthenticated server-side request forgery in the Pixelavo WordPress plugin before 1.5.4 allows any visitor to inject arbitrary Facebook conversion events using the site administrator's stored Conversions API access token. The plugin registers an AJAX endpoint protected only by a nonce that is emitted in plaintext on every public page load, rendering the nonce trivially obtainable and the endpoint effectively unprotected. Attackers can poison the administrator's Facebook Ads analytics with fabricated conversion data and exhaust the configured API quota, degrading ad targeting and measurement. A publicly available exploit exists; no confirmed active exploitation (CISA KEV) at time of analysis.
