Summary
Command Injection in hot-formula-parser
Details

Versions of hot-formula-parser prior to 3.0.1 are vulnerable to Command Injection. The package fails to sanitize values passed to the parse function and concatenates it in an eval call. If a value of the formula is supplied by user-controlled input it may allow attackers to run arbitrary commands in the server.
Parsing the following formula creates a test file in the present directory:
"SUM([(function(){require('child_process').execSync('touch test')})(),2])"

Recommendation

Upgrade to version 3.0.1 or later.

Severity ?
9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
