CVE-2024-13900Network attack vector

Administrator code execution via default multisite PHP

Published Feb 21, 2025 · Updated Apr 8, 2026

PHP code injection in Satollo Head, Footer and Post Injections 3.3.0 and earlier allows remote authenticated users to execute PHP. The plugin recognizes and executes saved PHP content while affected multisite installations leave that feature enabled without the later opt-in constant. Administrator-level access to a WordPress multisite is required, and injected PHP runs when a configured insertion point is rendered.
