{"apiVersion":"1.0","identifier":"CVE-2026-72701","description":"Grav CMS before 2.0.16 contains a timing vulnerability in Utils::verifyNonce() that uses non-constant-time string comparison with the === operator instead of hash_equals() for CSRF nonce validation. Attackers can measure response timing differences to recover valid nonce values byte-by-byte through multiple requests, weakening CSRF protection below its intended security margin.","publishedAt":"2026-08-25T02:16:45","lastModifiedAt":"2026-08-27T17:19:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72701","cvssScore":3.7,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00179,"riskScore":0.38,"affectedProduct":"Grav CMS","affectedVersions":"<2.0.16","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72701","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72701","en":"https://www.redsauce.net/en/cves/CVE-2026-72701","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72701","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72701","de":"https://www.redsauce.net/de/cves/CVE-2026-72701","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72701","el":"https://www.redsauce.net/el/cves/CVE-2026-72701"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72701"}}
