{"apiVersion":"1.0","identifier":"CVE-2026-72702","description":"Grav CMS before 2.0.16 contains an origin validation bypass in the Uri::referrer() and Pages::referrerRoute() methods, which validate the Referer header using an unanchored string prefix match (str_starts_with($referrer, $base)) with no trailing delimiter. An attacker who controls a domain that begins with the victim site-s origin (e.g. https://example.com.attacker.tld) can send a request with such a Referer to be treated as same-origin, bypassing the Referer-based origin check.","publishedAt":"2026-08-25T02:16:46","lastModifiedAt":"2026-08-25T02:16:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72702","cvssScore":5.4,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","epssProbability":0.00103,"riskScore":0.55,"affectedProduct":"Grav CMS","affectedVersions":"<2.0.16","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72702","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72702","en":"https://www.redsauce.net/en/cves/CVE-2026-72702","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72702","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72702","de":"https://www.redsauce.net/de/cves/CVE-2026-72702","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72702","el":"https://www.redsauce.net/el/cves/CVE-2026-72702"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72702"}}
