In Nuxt versions 3.1.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6 and @nuxt/nitro-server versions 3.20.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, the /__nuxt_island/* endpoint accepts attacker-controlled props query/body parameters and renders any island component without verifying that the URL-resident hash (<Name>_<hashId>.json) was actually issued for those inputs by <NuxtIsland>. The hash is computed and embedded client-side but never validated server-side, so the same path can return materially different responses depending on the query. This issue has been patched in versions 3.21.6 and 4.4.6.","published_at":"2026-06-12T12:50:41.589000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":2.3,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","cvss_v4_severity":"LOW","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79","CWE-349","CWE-444"],"nvd_references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-g8wj-3cr3-6w7v","https://github.com/nuxt/nuxt/pull/35077"],"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":"2026-06-28T23:30:38.004927Z"},"effective_severity":"LOW","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":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"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":"L","value_label":"Low"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"L","value_label":"Low"},{"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":">= 3.1.0, < 3.21.6","version_start_inclusive":true,"version_end":">= 3.1.0, < 3.21.6","version_end_inclusive":true,"cpe23_uri":"cve5:nuxt:nuxt:>= 3.1.0, < 3.21.6:>= 3.1.0, < 3.21.6"},{"vendor_slug":"nuxt","vendor_name":"Nuxt","product_slug":"nuxt","product_name":"Nuxt","version_start":">= 4.0.0-alpha.1, < 4.4.6","version_start_inclusive":true,"version_end":">= 4.0.0-alpha.1, < 4.4.6","version_end_inclusive":true,"cpe23_uri":"cve5:nuxt:nuxt:>= 4.0.0-alpha.1, < 4.4.6:>= 4.0.0-alpha.1, < 4.4.6"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-g8wj-3cr3-6w7v","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/nuxt/nuxt/pull/35077","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-12T12:50:41.589000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:49.174395Z","label":"CVSS score revised","source":"cvelistv5"}]}
