Technical Analysis
CVE-2026-110648 is an OS command injection vulnerability in the @offactory/compress-fonts package versions before 1.1.1. The vulnerability occurs because font file paths are inserted without proper quoting into a FontForge command executed through Node.js's child_process.execSync. This allows an attacker to craft font file names containing shell metacharacters, which are then executed with the privileges of the Node.js process running the package.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary shell commands on the host system with the privileges of the Node.js process running compress-fonts. This can lead to system compromise, data loss, or further attacks depending on the environment and privileges.
Mitigation Recommendations
Upgrade to version 1.1.1 or later of @offactory/compress-fonts where this vulnerability is fixed. Patch status is confirmed by the affectedVersions data indicating versions before 1.1.1 are vulnerable.
