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.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
