{"cve":"CVE-2026-53654","nvd":{"published":"2026-08-19T16:17:46.150","modified":"2026-09-09T21:13:25.910","status":"Deferred","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.","cvss_v4":{"vector":"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","score":5.3},"cvss_v3":null,"cwes":["CWE-601"],"references":["https://github.com/getgrav/grav-plugin-login/commit/1535e51d2a9cbc3f1bb1e262e791c142a06ce959","https://github.com/getgrav/grav-plugin-login/releases/tag/3.8.5","https://github.com/getgrav/grav/security/advisories/GHSA-wwcc-xxhc-44j6","https://github.com/getgrav/grav/security/advisories/GHSA-wwcc-xxhc-44j6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-53654","score":0.00526,"percentile":0.44605,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
