CVE-2023-49293 Information

Description

Vite is a website frontend framework. When Vite’s HTML transformation is invoked manually via server.transformIndexHtml the original request URL is passed in unmodified and the html being transformed contains inline module scripts (<script type=\module\>...</script>) it is possible to inject arbitrary HTML into the transformed output by supplying a malicious URL query string to server.transformIndexHtml. Only apps using appType: 'custom' and using the default Vite HTML middleware are affected. The HTML entry must also contain an inline script. The attack requires a user to click on a malicious URL while running the dev server. Restricted files aren’t exposed to the attacker. This issue has been addressed in vite@5.0.5 vite@4.5.1 and vite@4.4.12. There are no known workarounds for this vulnerability.
