{"id":"CVE-2026-45566","summary":"Roxy-WI: Open redirect on /login?next= via basic-auth userinfo syntax bypass","details":"Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the login flow allow-lists next URLs by rejecting strings containing https:// or http:// substrings, then constructs https://{request.host}{next_url} and the JS client redirects via window.location.replace(). The block does not consider the userinfo@host syntax. next=@evil.example/path produces https://victim.example@evil.example/path, which all modern browsers route to evil.example. At time of publication, there are no publicly available patches.","aliases":["GHSA-xw9x-68gg-mp5h"],"modified":"2026-07-15T01:48:55.623051397Z","published":"2026-06-10T15:36:10.592Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-601"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45566.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45566.json"},{"type":"ADVISORY","url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-xw9x-68gg-mp5h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45566"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roxy-wi/roxy-wi","events":[{"introduced":"0"},{"last_affected":"d72ea494d0bf1ee220fe141625a4298600f624ad"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"8.2.6.4"}],"source":"AFFECTED_FIELD"}}],"versions":["v8.2.6.4","v8.2.6.3","v8.2.8.2","v8.2.8.1","v8.2.6","v8.2.5","v8.2.4","v8.2.3","v8.2.2","v8.2.1","v8.2.0","v8.1.8","v8.1.7","v8.1.6","v8.1.5","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1.0.1","v8.1","v8.0.2","v8.0.1","v8.0","v7.3.2.0","v7.3.1.0","v7.3.0.0","v7.2.6.0","v7.2.5.0","v7.2.4.0","v7.2.3.0","v7.2.2.0","v7.2.1.0","v7.2.0.0","v7.1.2.0","v7.1.1.0","v7.1.0.0","v7.0.4.0","v7.0.3.0","v7.0.2.0","v7.0.1.0","v7.0.0.0","v6.3.19.0","v6.3.18.0","v6.3.17.0","v6.3.16.0","v6.3.15.0","v6.3.14.0","v6.3.13.0","v6.3.12.0","v6.3.11.0","v6.3.10.0","v6.3.9.0","v6.3.8.0","v6.3.7.0","v6.3.6.0","v6.3.5.0","v6.3.4.0","v6.3.3.0","v6.3.2.0","v6.3.1.0","v6.3.0.0","v6.2.3.0","v6.2.2.0","v6.2.1.0","v6.2.0.0","v6.1.5.0","v6.1.4.0","v6.1.3.0","v6.1.2.0","v6.1.1.0","v6.1.0.0","v6.0.3.0","v6.0.2.0","v6.0.1.0","v6.0.0.0","v5.5.1.0","v5.5.0.0","v5.4.3.0","v5.4.2.0","v5.4.1.0","v5.4.0.0","v5.3.6.0","v.5.3.5.0","v5.3.4.0","v5.3.3.0","v5.3.2.0","v5.3.1.0","v5.3.0.0","v5.2.6.0","v5.2.5.0","v5.2.4.0","v5.2.3.0","v5.2.2.0","v5.2.1","v5.2.0","v5.1.4.0","v5.1.1.0","v4.4.1.0","3.4.5.1","3.4.5","3.4.4.7","3.4.4.6","v3.3","v3.2.13","v2.0.2","v1.10.2.1","v1.10.2","v1.10.1","v1.10","v1.9.1","v1.6","v1.4.1","v1.4","v1.3","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45566.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
