CVE-2026-30309
InfCode Terminal Auto-Execution Module PowerShell Command Injection Vulnerability
Description
InfCode's terminal auto-execution module contains a critical command filtering vulnerability that renders its blacklist security mechanism completely ineffective. The predefined blocklist fails to cover native high-risk commands in Windows PowerShell (such as powershell), and the matching algorithm lacks dynamic semantic parsing unable to recognize string concatenation, variable assignment, or double-quote interpolation in Shell syntax. Malicious commands can bypass interception through simple syntax obfuscation. An attacker can construct a file containing malicious instructions for remote code injection. When a user imports and views such a file in the IDE, the Agent executes dangerous PowerShell commands outside the blacklist without user confirmation, resulting in arbitrary command execution or sensitive data leakage.
