CVE-2025-61787 – Deno is Vulnerable to Command Injection on Windows During Batch File Execution

CVE ID : CVE-2025-61787

Published : Oct. 8, 2025, 2:15 a.m. | 20 minutes ago

Description : Deno is a JavaScript, TypeScript, and WebAssembly runtime. 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.

Severity: 8.1 | HIGH
