Descriptions

m1k1o/blog is a lightweight self-hosted facebook-styled PHP blog. Errors from functions `imagecreatefrom*` and `image*` have not been checked properly. Although PHP issued warnings and the upload function returned `false`, the original file (that could contain a malicious payload) was kept on the disk. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

m1k1o/blog es un blog PHP ligero y auto-alojado al estilo de Facebook. Los errores de las funciones "imagecreatefrom*" y "image*" no han sido comprobados apropiadamente. Aunque PHP emitía advertencias y la función de carga devolvía "false", el archivo original (que podría contener una carga maliciosa) era mantenido en el disco. Es reacomendado a usuarios actualizar lo antes posible. No hay medidas de mitigación adicionales conocidas para este problema

m1k1o's Blog versions 1.3 and below suffer from an authenticated remote code execution vulnerability.
