CVE-2026-61597

Summary

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.
