Detailsinfo

A vulnerability, which was classified as problematic, has been found in adamarcanov compress-fonts up to 1.1.0.

Impacted is confidentiality, integrity, and availability. CVE summarizes:

@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.
