要点

CVE-2020-6836 は hot-formula-parser (hot-formula-parser project), hot-formula-parser に影響する深刻度「緊急」 (CVSS 9.8) の脆弱性です。
今後30日間に悪用される確率（EPSS）：2.1%（全脆弱性の 82.2% より高い）。
対処：3.0.1 以降に更新してください。

パッケージ	影響を受けるバージョン	修正済みバージョン
hot-formula-parser hot-formula-parser_project	`< 3.0.1`	`3.0.1`
hot-formula-parser npm	`< 3.0.1`	`3.0.1`

概要

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.

NVD の説明

grammar-parser.jison in the hot-formula-parser package before 3.0.1 for Node.js is vulnerable to arbitrary code injection. The package fails to sanitize values passed to the parse function and concatenates them in an eval call. If a value of the formula is taken from user-controlled input, it may allow attackers to run arbitrary commands on the server.
