Описание
Svelte performance oriented web framework. Prior to version 5.53.5, the contents of bind:innerText and bind:textContent on contenteditable elements were not properly escaped. This could enable HTML injection and Cross-Site Scripting (XSS) if rendering untrusted data as the binding's initial value on the server. Version 5.53.5 fixes the issue.
A flaw was found in svelte, a performance-oriented web framework. When rendering untrusted data as the initial value for bind:innerText and bind:textContent on contenteditable elements on the server, the contents were not properly escaped. This improper handling could allow a remote attacker to perform HTML injection and Cross-Site Scripting (XSS), leading to the execution of malicious scripts in the user's browser.
