Versions prior to 2.5.3 and 2.2.15 are vulnerable to Command Line Injection attacks on Windows when batch files are executed. In Windows, ``CreateProcess()`` always implicitly spawns ``cmd.exe`` if a batch file (.bat, .cmd, etc.) is being executed even if the application does not specify it via the command line. This makes Deno vulnerable to a command injection attack on Windows. Versions 2.5.3 and 2.2.15 fix the issue.\n\n## Affected\n\n- `deno <= 2.2.15`\n- `deno >= 2.3.0, < 2.5.3`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `deno 2.5.3`","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.4,"exploitation":0,"ransomware":0},"changes":[]}
