Executive brief
JetBrains GoLand, a popular development environment for the Go programming language, contained a vulnerability that could allow malicious code to run on a developer's computer. This could happen automatically when opening a project, even before the user has explicitly chosen to 'trust' the project files. An attacker could use this to gain full control over a developer's workstation, potentially stealing source code, credentials, or sensitive company data.
Technical details
An arbitrary code execution vulnerability exists in JetBrains GoLand's Go Modules integration. The flaw stems from improper control of code generation (CWE-94) where the IDE may execute commands or scripts associated with Go modules automatically upon opening a project. Crucially, this execution occurs before the 'Project Trust' security mechanism can intervene. An attacker can exploit this by tricking a user into opening a specially crafted project locally. Successful exploitation allows for full system compromise under the context of the current user. The issue is resolved in GoLand version 2026.2.
