CVE-2023-47621

Estado: ModificadaAlta (8.8)—

Guest Entries es una librería php que permite a los usuarios crear, actualizar y eliminar entradas desde el front-end de un sitio. En las versiones afectadas, la función de carga de archivos no impedía la carga de archivos PHP. Esto puede provocar la ejecución de código en el servidor por parte de usuarios autenticados. Esta vulnerabilidad se solucionó en v3.1.2. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
