CVE-2026-13604: CWE-918 Server-Side Request Forgery (SSRF) in Pixelavo
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.
AI Analysis
Technical Summary
The Pixelavo WordPress plugin prior to version 1.5.4 exposes an SSRF vulnerability (CWE-918) by registering an unauthenticated AJAX action. This action is gated solely by a nonce that is publicly emitted on every front-end page, enabling unauthenticated users to forward arbitrary event data to the Facebook Conversions API using the administrator's stored access token. This can lead to injection of arbitrary conversion events into the administrator's Facebook ads account and exhaustion of the configured API quota.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to inject arbitrary conversion events into the administrator's Facebook ads account. This may result in exhaustion of the Facebook Conversions API quota, potentially disrupting legitimate advertising tracking and causing financial or operational impact related to ad campaign management.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the AJAX action if possible and monitor for unusual API usage. Avoid relying solely on publicly exposed nonces for authentication of sensitive actions.
