Because Vary is a response header that should be managed by the server, an attacker can supply arbitrary Vary values that are reflected into the response, potentially causing cache key pollution and inconsistent CORS enforcement in environments that rely on shared caches or proxies.","score":6.9,"severity":"medium","published":"2026-06-30T22:08:21.523Z","modified":"2026-10-29T21:15:18.744Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Hono","name":"Hono","platforms":[],"versions":[{"version":"0","status":"affected","lessThan":"4.10.3","versionType":"semver"},{"version":"4.10.3","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:npm/hono","packageIdentity":{"ecosystem":"npm","name":"hono"},"cpes":[],"source":"VulnCheck","url":"https://www.cve.org/CVERecord?id=CVE-2025-71381"}],"remediation":[],"references":["https://github.com/honojs/hono/security/advisories/GHSA-q7jf-gf43-6x6p","https://www.vulncheck.com/advisories/hono-vary-header-injection-in-cors-middleware"],"sources":[{"name":"CVE","id":"CVE-2025-71381","modified":"2026-10-29T21:15:18.744Z","url":"https://www.cve.org/CVERecord?id=CVE-2025-71381"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.9},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5}],"sourceAffected":[],"observedAt":"2026-10-29T21:39:12.461Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T17:10:32.267Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T00:45:31.407Z","attemptedAt":"2026-10-30T00:45:31.407Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-30T00:45:31.407Z","attemptedAt":"2026-10-30T00:45:31.407Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-30T00:45:31.407Z","attemptedAt":"2026-10-30T00:45:31.407Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-30T00:45:31.407Z","attemptedAt":"2026-10-30T00:45:31.407Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2025-210393","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-210393","modified":"Oct 29, 2026, 9:15:18 PM","score":6.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","checkedAt":"2026-10-30T00:45:31.407Z"},{"source":"FIRST EPSS","id":"CVE-2025-71381","url":"https://www.first.org/epss/","probability":0.00292,"percentile":0.21766,"date":"2026-10-29","checkedAt":"2026-10-30T00:45:31.407Z"},{"source":"GitHub Advisory Database","id":"GHSA-q7jf-gf43-6x6p","url":"https://github.com/advisories/GHSA-q7jf-gf43-6x6p","modified":"2026-10-02T18:28:56Z","score":4.2,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","checkedAt":"2026-10-30T00:45:31.407Z"},{"source":"NVD","id":"CVE-2025-71381","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71381","modified":"2026-10-29T21:17:05.513","score":6.9,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","checkedAt":"2026-10-30T00:45:31.407Z"},{"source":"NVD","id":"CVE-2025-71381","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71381","modified":"2026-10-29T21:17:05.513","score":6.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","checkedAt":"2026-10-30T00:45:31.407Z"}],"aiSummary":null}
