Prior to version 10.0.2, the @astrojs/vercel serverless entrypoint reads the x-astro-path header and x_astro_path query parameter to rewrite the internal request path, with no authentication whatsoever. On deployments without Edge Middleware, this lets anyone bypass Vercel's platform-level path restrictions entirely. The override preserves the original HTTP method and body, so this isn't limited to GET. POST, PUT, DELETE all land on the rewritten path. A Firewall rule blocking /admin/* does nothing when the request comes in as POST /api/health?x_astro_path=/admin/delete-user. This issue has been patched in version 10.0.2.","published_at":"2026-03-24T18:40:12.549000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-441","CWE-862"],"nvd_references":["https://github.com/withastro/astro/security/advisories/GHSA-mr6q-rp88-fx84","https://github.com/withastro/astro/pull/15959","https://github.com/withastro/astro/commit/335a204161f5a7293c128db570901d4f8639c6ed","https://github.com/withastro/astro/releases/tag/%40astrojs%2Fvercel%4010.0.2"],"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":"2026-06-28T23:29:55.932242Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"withastro","vendor_name":"withastro","product_slug":"astro","product_name":"astro","version_start":"< 10.0.2","version_start_inclusive":true,"version_end":"< 10.0.2","version_end_inclusive":true,"cpe23_uri":"cve5:withastro:astro:< 10.0.2:< 10.0.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/withastro/astro/security/advisories/GHSA-mr6q-rp88-fx84","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/withastro/astro/pull/15959","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/withastro/astro/commit/335a204161f5a7293c128db570901d4f8639c6ed","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/withastro/astro/releases/tag/%40astrojs%2Fvercel%4010.0.2","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-03-24T18:40:12.549000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"}]}
