{"cve":"CVE-2026-53722","nvd":{"published":"2026-06-12T15:16:31.427","modified":"2026-06-17T10:58:00.153","status":"Analyzed","description":"Nuxt is an open-source web development framework for Vue.js. Prior to versions 3.21.7 and 4.4.7, <NuxtLink> did not validate the URL scheme of values bound to its to or href props before rendering them into the href attribute of the underlying <a> element. When an application binds attacker-controlled input (a query parameter, a CMS field, a user-supplied profile URL) to <NuxtLink :to> or :href, the attacker can supply a javascript: or vbscript: URL that is reflected verbatim into the rendered markup. Clicking the link executes the supplied script in the origin of the Nuxt application, resulting in reflected DOM-based cross-site scripting. A data:text/html,... payload reflected through the same sink does not execute in the application's origin but enables a same-tab phishing surface anchored to a legitimate application link. The same value was exposed to consumers of the component's custom slot via the href and route.href props, so applications that re-bind those values to their own anchors were affected identically. This issue has been patched in versions 3.21.7 and 4.4.7.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79","CWE-83"],"references":["https://github.com/nuxt/nuxt/commit/0103ce06fbbbdfa079a7f020ef8ce00121eac4a3","https://github.com/nuxt/nuxt/commit/53284043dc21210a25d629d1cec67d3ae557ffd0","https://github.com/nuxt/nuxt/security/advisories/GHSA-934w-87qh-qr26"],"products":["nuxt:nuxt"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-53722","score":0.00293,"percentile":0.21928,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-934w-87qh-qr26","url":"https://osv.dev/vulnerability/GHSA-934w-87qh-qr26","summary":"Nuxt: Reflected XSS in `<NuxtLink>` via unsanitised `javascript:` or `data:` URL","modified":"2026-08-14T19:00:07.654547013Z","packages":[{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=4.0.0 <4.4.7"],"fixed":["4.4.7"]},{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=3.0.0 <3.21.7"],"fixed":["3.21.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
