{"apiVersion":"1.0","identifier":"CVE-2026-53654","description":"Grav is a file-based Web platform. Prior to 3.8.5, the Login plugin twofa_cancel task accepts a client-controlled _redirect field without a nonce and allows an unauthenticated request to set an external http, https, or protocol-relative Location target. Controller::execute() applies the field when taskTwofa_cancel() sets no redirect, and Grav::getRedirectResponse() accepts the target through Uri::isExternal(), enabling phishing redirects from a trusted Grav host. This issue is fixed in version 3.8.5.","publishedAt":"2026-08-19T16:17:46","lastModifiedAt":"2026-08-19T16:17:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53654","cvssScore":5.3,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/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","epssProbability":0.00386,"riskScore":0.55,"affectedProduct":"Grav","affectedVersions":"<3.8.5","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53654","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53654","en":"https://www.redsauce.net/en/cves/CVE-2026-53654","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53654","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53654","de":"https://www.redsauce.net/de/cves/CVE-2026-53654","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53654","el":"https://www.redsauce.net/el/cves/CVE-2026-53654"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53654"}}
