CVE-2024-53261

描述

### Summary "Unsanitized input from *the request URL* flows into `end`, where it is used to render an HTML page returned to the user. This may result in a Cross-Site Scripting attack (XSS)." ### Details Source of potentially tainted data is in `packages/kit/src/exports/vite/dev/index.js`, line 437. This potentially tainted data is passed through a number of steps (which I could detail if you'd like) all the way down to line 91 in `packages/kit/src/exports/vite/utils.js`, which performs an operation that Snyk believes an attacker shouldn't be allowed to manipulate. Another source of potentially tainted data (according to Snyk) comes from `‎packages/kit/src/exports/vite/utils.js`, line 30, col 30 (i.e., the `url` property of `req`). This potentially tainted data is passed through a number of steps (which I could detail if you'd like) all the way down line 91 in `packages/kit/src/exports/vite/utils.js`, which performs an operation that Snyk believes an attacker shouldn't be allowed to manipulate. ### PoC Not provided ### Impact Little to none. The Vite development is not exposed to the network by default. And even if someone were able to trick a developer into executing an XSS against themselves, a development database should not have any sensitive data.
