CVE-2026-30305Public exploitNetwork attack vector

Unauthenticated command execution via shell substitution

Published Mar 30, 2026 · Updated Mar 30, 2026

OS command injection in Orangecat Technologies Syntx 2.5.0 and earlier allows remote attackers to execute arbitrary commands via crafted tool calls. The command auto-approval module uses regular expressions to classify shell strings but fails to reject command substitution in arguments, including $() and backticks. A crafted argument is approved as a safe Git operation before the shell expands and executes the embedded command without user interaction.
