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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-601"],"references":["https://github.com/tenancy/multi-tenant/commit/9c837a21bccce9bcaeb90033ef200d84f0d9e164","https://github.com/tenancy/multi-tenant/security/advisories/GHSA-4r8q-gv9j-3xx6","https://packagist.org/packages/hyn/multi-tenant","https://webmasters.googleblog.com/2009/01/open-redirect-urls-is-your-site-being.html","https://github.com/tenancy/multi-tenant/commit/9c837a21bccce9bcaeb90033ef200d84f0d9e164"],"products":["tenancy:multi-tenant"],"source":"nvd","synced_at":"2026-10-19T21:18:09.669877188+00:00"},"epss":{"cve":"CVE-2021-32645","score":0.0102,"percentile":0.63411,"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).
