# CVE-2026-110648

> 8.5 HIGH · 🧪 PoC

## Beschreibung

@offactory/compress-fonts before 1.1.1 contains an OS command injection vulnerability that allows attackers to execute shell commands by supplying font files with crafted names. Font paths are interpolated unquoted into a FontForge command run through child_process.execSync, so shell metacharacters in file names execute commands with the Node.js process privileges.

## Schwachstellen-Klasse

- **CWE-78** — Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
  The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
