{"cve":"CVE-2025-58067","nvd":{"published":"2025-08-29T21:15:36.480","modified":"2026-10-18T21:10:00.120","status":"Deferred","description":"Basecamp's Google Sign-In adds Google sign-in to Rails applications. Prior to version 1.3.1, it is possible to redirect a user to another origin if the \"proceed_to\" value in the session store is set to a protocol-relative URL. Normally the value of this URL is only written and read by the library or the calling application. However, it may be possible to set this session value from a malicious site with a form submission. Any Rails applications using the google_sign_in gem may be vulnerable, if this vector can be chained with another attack that is able to modify the OAuth2 request parameters. This issue has been patched in version 1.3.1. There are no workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","score":4.2},"cwes":["CWE-601"],"references":["https://github.com/basecamp/google_sign_in/commit/e97aef4626b1bcbd2c6f01f7dd25f12ac855d4cc","https://github.com/basecamp/google_sign_in/pull/75","https://github.com/basecamp/google_sign_in/releases/tag/v1.3.1","https://github.com/basecamp/google_sign_in/security/advisories/GHSA-5jch-xhw4-r43v"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-58067","score":0.00226,"percentile":0.13199,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5jch-xhw4-r43v","url":"https://osv.dev/vulnerability/GHSA-5jch-xhw4-r43v","summary":"Google Sign-In for Rails allowed redirect to protocol-relative URI","modified":"2025-09-01T20:58:23.736800Z","packages":[{"ecosystem":"RubyGems","name":"google_sign_in","purl":"pkg:gem/google_sign_in","ranges":["<1.3.1"],"fixed":["1.3.1"]}]}],"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).
