CVE-2026-61597 Details
Description
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, many djust built-in component template tags (`djust.components.templatetags.*`) render a developer/user-supplied URL into an `href` / `action` attribute, HTML-escaping it with `conditional_escape` but never validating the URL scheme. HTML escaping prevents attribute breakout but does not neutralize a `javascript:` URI (which needs no escapable characters), so a URL value of `javascript:alert(document.cookie)` lands verbatim in `<a href="javascript:alert(document.cookie)">` and executes in the victim's session on click. Version 1.0.7 contains a fix. As a workaround, do not pass user-controllable URLs to the affected built-in component tags; pre-validate URL schemes in application code before binding them to component arguments.
A cross-site scripting (XSS) vulnerability has been identified in djust, a Django library that offers reactive server-side rendering with enhanced performance. This issue affects versions prior to 1.0.7. The vulnerability arises because several built-in component template tags render user-supplied URLs into attributes such as 'href' or 'action'. While these URLs are HTML-escaped to prevent attribute breakout, there is no validation of the URL scheme. As a result, a 'javascript:' URI can be injected and executed in the context of the user's session when the link is clicked. This vulnerability is particularly concerning in components that store URLs, as it can lead to persistent XSS.
Users can upgrade to djust version 1.0.7, which addresses this vulnerability. For those unable to upgrade, it is recommended to pre-validate URL schemes in application code before using them with djust's built-in component tags.
