CVE-2025-26979Network attack vector

Unauthenticated local file inclusion

Published Feb 25, 2025 · Updated Apr 28, 2026

Local file inclusion in FunnelKit Funnel Builder 3.9.0 and earlier allows remote attackers to include server files via web requests. Public advisories do not identify the affected endpoint, filename parameter, or include/require call that accepts untrusted input. Exploitation requires no privileges but does require user interaction and high-complexity conditions; included PHP files execute in the WordPress server context.
