H Access Restriction Bypass xmlhttprequest-ssl is a fork of `xmlhttprequest`. Affected versions of this package are vulnerable to Access Restriction Bypass. The package disables SSL certificate validation by default, because `rejectUnauthorized` (when the property exists but is undefined) is considered to be false within the `https.request` function of Node.js. In other words, no certificate is ever rejected. How to fix Access Restriction Bypass? Upgrade `xmlhttprequest-ssl` to version 1.6.1 or higher.	<1.6.1
H Arbitrary Code Injection xmlhttprequest-ssl is a fork of `xmlhttprequest`. Affected versions of this package are vulnerable to Arbitrary Code Injection. Provided requests are sent synchronously (`async=False` on `xhr.open`), malicious user input flowing into `xhr.send` could result in arbitrary code being injected and run. POC `const { XMLHttpRequest } = require("xmlhttprequest") const xhr = new XMLHttpRequest() xhr.open("POST", "http://localhost.invalid/", false /* use synchronize request */) xhr.send("\\');require(\"fs\").writeFileSync(\"/tmp/aaaaa.txt\", \"poc-20210306\");req.end();//")` How to fix Arbitrary Code Injection?
