Executive brief
JetBrains GoLand, a popular development environment for the Go programming language, was vulnerable to a security flaw that could allow an attacker to execute malicious code on a developer's computer. This occurs when a user opens or interacts with a specially crafted, untrusted project configuration file. An exploit could lead to full system compromise, theft of source code, or unauthorized access to corporate development environments.
Technical details
A remote code execution vulnerability exists in JetBrains GoLand versions prior to 2026.1.3. The flaw is rooted in the improper handling of external control of file names or paths (CWE-73) within project configuration files. An attacker can exploit this by tricking a user into opening a malicious project or importing a compromised configuration. Successful exploitation allows for arbitrary code execution in the context of the IDE process. The vulnerability requires user interaction (UI:R) but can be initiated over the network (AV:N) if a user downloads and opens a malicious repository. JetBrains has addressed this issue in version 2026.1.3.
