CVE-2026-30309

Arbitrary command execution via blacklist bypass

Published Mar 31, 2026 · Updated Mar 31, 2026

Command injection in Tokfinity InfCode 1.3.1 and earlier allows attackers to execute arbitrary PowerShell commands through a crafted file. The terminal auto-execution module uses a static blocklist that omits native PowerShell commands and fails to parse concatenation, variable assignment, or quote interpolation. Execution requires a user to import and view the file in the IDE, after which the Agent runs the obfuscated command without confirmation, enabling code execution and sensitive-data disclosure.
