Command Injection in hot-formula-parser

Source: GitHub Advisory Database (reviewed) Critical CVE-2020-6836

Packages

EcosystemPackageAffectedFixed in
npm hot-formula-parser < 3.0.1 3.0.1

Details

As written in the advisory (Markdown source, shown as plain text).

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.
