CVE-2024-34343
Nuxt
CVE-2024-34343 affects Nuxt web applications, potentially allowing for cross-site scripting (XSS) attacks due to improper URL parsing in the navigateTo
function. While the CVSS score is 6.1, the SOCRadar Vulnerability Risk Score (SVRS) is 38, indicating a moderate risk. This vulnerability arises from discrepancies within the unjs/ufo library used by Nuxt, where parsing inconsistencies can bypass protocol checks meant to block javascript:
URLs. Specifically, the library's parseURL
function fails to properly parse or sanitize certain malformed URLs, leading to script execution. This issue manifests after server-side rendering (SSR) has occurred, potentially exposing users to XSS attacks through crafted location headers. The recommended solution is to upgrade to Nuxt version 3.12.4, which addresses this parsing flaw, and there are no known workarounds. Although not considered critical based on the SVRS, promptly patching remains essential to mitigate potential exploits.
Description
CVE-2024-34343 affects Nuxt, a framework for creating web applications with Vue.js. The vulnerability stems from the navigateTo
