CVE-2026-112303
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.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
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.
