{"id":"CVE-2026-45552","summary":"Roxy-WI: Cross-tenant authorization bypass on /install/* — guest can run Ansible / SSH on every registered server","details":"Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the install blueprint declares only bp.before_request → @jwt_required() (app/routes/install/routes.py:36-39). The individual endpoints install_exporter, install_waf, install_geoip, check_geoip, get_exporter_version, and get_task_status are not wrapped in page_for_admin and do not call roxywi_common.is_user_has_access_to_its_group(server_ip) or check_is_server_in_group(server_ip). Only the GET index page (install_monitoring) gates on roxywi_auth.page_for_admin(level=2). Because the missing decorators omit both role and group checks, any logged-in user — including the default guest role 4 — can install/reconfigure exporters, WAF, and GeoIP databases on every server in the Roxy-WI database, regardless of tenant ownership. The Ansible playbooks run with the per-server SSH credential stored in Roxy-WI, which the credentials' rightful owner (a different tenant) has provisioned with sudo rights for the management workflow. At time of publication, there are no publicly available patches.","aliases":["GHSA-v3f8-g2v8-jq5h"],"modified":"2026-07-15T01:48:58.849780418Z","published":"2026-06-10T13:59:24.337Z","database_specific":{"cwe_ids":["CWE-639","CWE-862","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45552.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45552.json"},{"type":"ADVISORY","url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-v3f8-g2v8-jq5h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45552"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roxy-wi/roxy-wi","events":[{"introduced":"0"},{"last_affected":"d72ea494d0bf1ee220fe141625a4298600f624ad"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"8.2.6.4"}]}}],"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-2026-45552.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
