CVE-2026-30120Network attack vector

Unauthenticated code execution via file-explorer command injection

Published Jun 15, 2026 · Updated Jun 15, 2026

Command injection in Remotion Studio 4.0.409 allows remote attackers to execute arbitrary code through a crafted file-explorer request. On Windows, the /api/open-in-file-explorer route embeds an attacker-controlled resolved path in an exec-built explorer.exe command without neutralizing shell metacharacters. The Studio server must be network-reachable, and successful exploitation runs commands with the Studio process's privileges.
