CVE-2022-29078
Severity: 9.8/ 10
Affected versions: < 3.1.7
Patched versions: 3.1.7

The ejs (aka Embedded JavaScript templates) package 3.1.6 for Node.js allows server-side template injection in settings[view options][outputFunctionName]. This is parsed as an internal option, and overwrites the outputFunctionName option with an arbitrary OS command (which is executed upon template compilation).
