5.46.1→5.46.4GitHub Vulnerability Alerts
CVE-2025-15265
Summary
An XSS vulnerability exists in Svelte 5.46.0-2 resulting from improper escaping of
hydratablekeys. If these keys incorporate untrusted user input, arbitrary JavaScript can be injected into server-rendered HTML.Details
When using the
hydratablefunction, the first argument is used as a key to uniquely identify the data, such that the value is not regenerated in the browser.This key is embedded into a
<script>block in the server-rendered<head>without escaping unsafe characters. A malicious key can break out of the script context and inject arbitrary JavaScript into the HTML response.Impact
This is a cross-site scripting vulnerability affecting applications that have the
experimental.asyncflag enabled and usehydratablewith keys incorporating untrusted user input.Affected applications should upgrade to a patched version immediately.
