CVE-2026-64802

Code execution via pre-trust Go Modules processing

Published Jul 23, 2026 · Updated Jul 23, 2026

Code injection in JetBrains GoLand before 2026.2 allows local users to execute arbitrary code through a crafted Go Modules project. The Go Modules integration processes attacker-controlled project content before the project-trust gate, but JetBrains has not disclosed the exact code path or unsafe operation. A user must open the crafted project; resulting code runs with the IDE user's privileges.
