CVE-2022-39298

MelisFront is the engine that displays website hosted on Melis Platform. It deals with showing pages, plugins, URL rewritting, search optimization and SEO, etc. Attackers can deserialize arbitrary data on affected versions of melisplatform/melis-front, and ultimately leads to the execution of arbitrary PHP code on the system. Conducting this attack does not require authentication. Users should immediately upgrade to melisplatform/melis-front >= 5.0.1. This issue was addressed by restricting allowed classes when deserializing user-controlled data.
