{"id":"CVE-2026-61597","state":"PUBLISHED","title":"djust is vulnerable to stored/reflected XSS via javascript: URLs in built-in component template tags","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.","publishedAt":"2026-09-16T21:51:38.339Z","updatedAt":"2026-09-17T15:06:13.521Z","severity":{"score":5.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["djust-org djust"],"affected":[{"vendor":"djust-org","product":"djust","versions":[{"version":"< 1.0.7","status":"affected"}]}],"references":["https://github.com/djust-org/djust/security/advisories/GHSA-4mf4-73j6-mvrw","https://github.com/djust-org/djust/releases/tag/v1.0.7"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61597.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61597","state":"PUBLISHED","datePublished":"2026-09-16T21:51:38.339Z","dateUpdated":"2026-09-17T15:06:13.521Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T17:12:17.238Z"},"containers":{"cna":{"title":"djust is vulnerable to stored/reflected XSS via javascript: URLs in built-in component template tags","descriptions":[{"lang":"en","value":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance.
