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.","published_at":"2026-06-12T13:44:14.592000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":5.1,"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","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79","CWE-83"],"nvd_references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-934w-87qh-qr26","https://github.com/nuxt/nuxt/commit/0103ce06fbbbdfa079a7f020ef8ce00121eac4a3","https://github.com/nuxt/nuxt/commit/53284043dc21210a25d629d1cec67d3ae557ffd0"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:53.124161Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"A","value_label":"Active"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"nuxt","vendor_name":"Nuxt","product_slug":"nuxt","product_name":"Nuxt","version_start":"< 3.21.7","version_start_inclusive":true,"version_end":"< 3.21.7","version_end_inclusive":true,"cpe23_uri":"cve5:nuxt:nuxt:< 3.21.7:< 3.21.7"},{"vendor_slug":"nuxt","vendor_name":"Nuxt","product_slug":"nuxt","product_name":"Nuxt","version_start":">= 4.0.0, < 4.4.7","version_start_inclusive":true,"version_end":">= 4.0.0, < 4.4.7","version_end_inclusive":true,"cpe23_uri":"cve5:nuxt:nuxt:>= 4.0.0, < 4.4.7:>= 4.0.0, < 4.4.7"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-934w-87qh-qr26","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/nuxt/nuxt/commit/0103ce06fbbbdfa079a7f020ef8ce00121eac4a3","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/nuxt/nuxt/commit/53284043dc21210a25d629d1cec67d3ae557ffd0","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-12T13:44:14.592000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:28.590503Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:28.590503Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:28.590503Z","label":"CVSS score revised","source":"cvelistv5"}]}
