What it is

GDevelop desktop app through 5.6.284 contains a credential leak vulnerability that allows attackers to steal the gd_resource cookie by supplying attacker-controlled resource URLs in project files. Attackers can get victims to open a crafted project, causing downloadLocalFile() to send the cookie to their server and expose private cloud project resources.
