{"id":"CVE-2021-32645","aliases":["GHSA-4r8q-gv9j-3xx6"],"url":"https://o3.security/vulnerability/CVE-2021-32645","summary":"Open Redirect","details":"Tenancy multi-tenant is an open source multi-domain controller for the Laravel web framework. In some situations, it is possible to have open redirects where users can be redirected from your site to any other site using a specially crafted URL. This is only the case for installations where the default Hostname Identification is used and the environment uses tenants that have `force_https` set to `true` (default: `false`). Version 5.7.2 contains the relevant patches to fix this bug. Stripping the URL from special characters to prevent specially crafted URL's from being redirected to. As a work around users can set the `force_https` to every tenant to `false`, however this may degrade connection security.","published":"2021-05-27T17:15:08.127Z","modified":"2026-07-09T12:20:09.371074Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"hyn/multi-tenant","fixedVersion":"5.7.2"}],"fix":{"url":"https://github.com/tenancy/multi-tenant/commit/9c837a21bccce9bcaeb90033ef200d84f0d9e164","label":"tenancy/multi-tenant@9c837a2"},"references":[{"type":"ADVISORY","url":"https://github.com/tenancy/multi-tenant/security/advisories/GHSA-4r8q-gv9j-3xx6"},{"type":"ADVISORY","url":"https://packagist.org/packages/hyn/multi-tenant"},{"type":"ADVISORY","url":"https://webmasters.googleblog.com/2009/01/open-redirect-urls-is-your-site-being.html"},{"type":"FIX","url":"https://github.com/tenancy/multi-tenant/commit/9c837a21bccce9bcaeb90033ef200d84f0d9e164"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T12:20:09.371074Z"}}
