{"id":"CVE-2026-61597","summary":"djust is vulnerable to stored/reflected XSS via javascript: URLs in built-in component template tags","details":"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 `\u003ca href=\"javascript:alert(document.cookie)\"\u003e` 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.","aliases":["GHSA-4mf4-73j6-mvrw"],"modified":"2026-09-17T11:45:27.199879362Z","published":"2026-09-16T21:51:38.339Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61597.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61597.json"},{"type":"WEB","url":"https://github.com/djust-org/djust/releases/tag/v1.0.7"},{"type":"ADVISORY","url":"https://github.com/djust-org/djust/security/advisories/GHSA-4mf4-73j6-mvrw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61597"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/djust-org/djust","events":[{"introduced":"0"},{"fixed":"e7f6751723e76219d3062f3391231fec3c736ab3"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"1.0.7"}]}}],"versions":["v1.0.7rc1","v1.0.6","v1.0.6rc3","v1.0.6rc2","v1.0.6rc1","v1.0.5","v1.0.5rc5","v1.0.5rc4","v1.0.5rc3","v1.0.5rc2","v1.0.5rc1","v1.0.4","v1.0.4rc1","v1.0.3","v1.0.3rc2","v1.0.3rc1","v1.0.2","v1.0.2rc3","v1.0.2rc2","v1.0.2rc1","v1.0.1","v1.0.1rc1","v1.0.0","v1.0.0rc18","v1.0.0rc17","v1.0.0rc16","v1.0.0rc15","v1.0.0rc14","v1.0.0rc13","v1.0.0rc12","v1.0.0rc11","v1.0.0rc10","v1.0.0rc9","v1.0.0rc8","v1.0.0rc7","v1.0.0rc6","v1.0.0rc4","v1.0.0rc3","v1.0.0rc2","v1.0.0rc1","v0.9.7","v0.9.7rc3","v0.9.7rc2","v0.9.7rc1","v0.9.6","v0.9.6rc3","v0.9.6rc2","v0.9.6rc1","v0.9.5","v0.9.5rc4","v0.9.5rc3","v0.9.5rc2","v0.9.5rc1","v0.9.4","v0.9.4rc9","v0.9.4rc8","v0.9.4rc7","v0.9.4rc6","v0.9.4rc5","v0.9.4rc3","v0.9.4rc2","v0.9.4rc1","v0.9.3rc2","v0.9.2rc2","v0.9.3rc1","v0.9.2","v0.9.2rc1","v0.9.1","v0.9.0","v0.9.0rc5","v0.9.0rc4","v0.9.0rc3","v0.9.0rc2","v0.9.0rc1","v0.8.8rc2","v0.8.8rc1","v0.8.7rc1","v0.8.6rc1","v0.8.5rc1","v0.8.4rc1","v0.8.3rc1","v0.8.2rc1","v0.8.0rc1","v0.7.4rc1","v0.7.3rc1","v0.7.2rc1","v0.7.1rc1","v0.7.0rc1","v0.6.1rc1","v0.6.0rc1","v0.5.7rc1","v0.5.6rc1","v0.5.5rc1","v0.5.4rc1","v0.5.3rc1","v0.5.2rc1","v0.5.1rc4","v0.5.1rc2","v0.5.1rc1","v0.5.0rc2","v0.5.0rc1","v0.4.5rc2","v0.4.5rc1","v0.4.4","v0.4.4rc1","v0.4.3","v0.4.3rc1","v0.4.2","v0.4.2rc4","v0.4.2rc3","v0.4.2rc2","v0.4.2rc1","v0.4.1","v0.4.1rc2","v0.4.1rc1","v0.4.0","v0.4.0rc3","v0.3.8","v0.3.8rc1","v0.3.7","v0.3.7rc2","v0.3.7rc1","v0.3.6","v0.3.6rc4","v0.3.6rc3","v0.3.6rc2","v0.3.6rc1","v0.3.5","v0.3.5rc2","v0.3.5rc1","v0.3.4","v0.3.3rc3","v0.3.3rc2","v0.3.3rc1","v0.3.2rc1","v0.3.1","v0.3.0","v0.3.0rc5","v0.3.0rc4","v0.3.0rc3","v0.3.0rc2","v0.3.0rc1","v0.2.2","v0.2.2rc5","v0.2.2rc3","v0.2.2rc2","v0.2.2rc1","v0.2.1","v0.2.1a1","v0.2.0","v0.2.0a2","v0.2.0a1","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-61597.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
