What is CVE-2026-79632?

The WPFunnels WordPress plugin before version 3.13.0 has a significant vulnerability that lacks proper authorization or nonce checks in an opt-in submission handler. This oversight enables unauthenticated users to exploit the system, potentially sending emails to any recipient with a chosen subject line. This vulnerability poses a risk of email spoofing, which can be detrimental to the affected site’s integrity and user trust. It is crucial for site administrators to update to the latest version to mitigate these risks.
