CVE-2025-59458Network attack vector

Code execution via improper command validation

Published Sep 17, 2025 · Updated Sep 17, 2025

Command injection in affected JetBrains Junie builds allows remote attackers to execute code after required user interaction. Junie improperly validates commands before execution, but JetBrains has not disclosed the affected function, input path, or validation failure. The attack requires no prior privileges but does require user interaction, and successful exploitation runs attacker-controlled commands in the Junie execution context.
