Prior to version 8.2.6.3, a command injection vulnerability exists in the `/config/compare/\u003cservice\u003e/\u003cserver_ip\u003e/show` endpoint, allowed authenticated users to execute arbitrary system commands on the app host. The vulnerability exists in `app/modules/config/config.py` on line 362, where user input is directly formatted in the template string that is eventually executed. Version 8.2.6.3 fixes the issue.","aliases":["GHSA-jvmv-cw47-jh77"],"modified":"2026-04-02T13:26:32.671842Z","published":"2026-03-17T23:43:05.871Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-77","CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27811.json"},"references":[{"type":"WEB","url":"https://github.com/roxy-wi/roxy-wi/releases/tag/v8.2.6.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27811.json"},{"type":"ADVISORY","url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-jvmv-cw47-jh77"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27811"},{"type":"FIX","url":"https://github.com/roxy-wi/roxy-wi/commit/a10ac7306c252014f97a7213db4a9470300fa064"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hap-wi/roxy-wi","events":[{"introduced":"0"},{"fixed":"a10ac7306c252014f97a7213db4a9470300fa064"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"8.2.6.3"}]}}],"versions":["3.4.4.6","3.4.4.7","3.4.5","3.4.5.1","v.5.3.5.0","v1.0","v1.1","v1.10","v1.10.1","v1.10.2","v1.10.2.1","v1.3","v1.4","v1.4.1","v1.6","v1.9.1","v2.0.2","v3.2.13","v3.3","v4.4.1.0","v5.1.1.0","v5.1.4.0","v5.2.0","v5.2.1","v5.2.2.0","v5.2.3.0","v5.2.4.0","v5.2.5.0","v5.2.6.0","v5.3.0.0","v5.3.1.0","v5.3.2.0","v5.3.3.0","v5.3.4.0","v5.3.6.0","v5.4.0.0","v5.4.1.0","v5.4.2.0","v5.4.3.0","v5.5.0.0","v5.5.1.0","v6.0.0.0","v6.0.1.0","v6.0.2.0","v6.0.3.0","v6.1.0.0","v6.1.1.0","v6.1.2.0","v6.1.3.0","v6.1.4.0","v6.1.5.0","v6.2.0.0","v6.2.1.0","v6.2.2.0","v6.2.3.0","v6.3.0.0","v6.3.1.0","v6.3.10.0","v6.3.11.0","v6.3.12.0","v6.3.13.0","v6.3.14.0","v6.3.15.0","v6.3.16.0","v6.3.17.0","v6.3.18.0","v6.3.19.0","v6.3.2.0","v6.3.3.0","v6.3.4.0","v6.3.5.0","v6.3.6.0","v6.3.7.0","v6.3.8.0","v6.3.9.0","v7.0.0.0","v7.0.1.0","v7.0.2.0","v7.0.3.0","v7.0.4.0","v7.1.0.0","v7.1.1.0","v7.1.2.0","v7.2.0.0","v7.2.1.0","v7.2.2.0","v7.2.3.0","v7.2.4.0","v7.2.5.0","v7.2.6.0","v7.3.0.0","v7.3.1.0","v7.3.2.0","v8.0","v8.0.1","v8.0.2","v8.1","v8.1.0.1","v8.1.1","v8.1.2","v8.1.3","v8.1.4","v8.1.5","v8.1.6","v8.1.7","v8.1.8","v8.2.0","v8.2.1","v8.2.2","v8.2.3","v8.2.4","v8.2.5","v8.2.6","v8.2.8.1","v8.2.8.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27811.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/roxy-wi/roxy-wi","events":[{"introduced":"0"},{"fixed":"a10ac7306c252014f97a7213db4a9470300fa064"}]}],"versions":["3.4.4.6","3.4.4.7","3.4.5","3.4.5.1","v.5.3.5.0","v1.0","v1.1","v1.10","v1.10.1","v1.10.2","v1.10.2.1","v1.3","v1.4","v1.4.1","v1.6","v1.9.1","v2.0.2","v3.2.13","v3.3","v4.4.1.0","v5.1.1.0","v5.1.4.0","v5.2.0","v5.2.1","v5.2.2.0","v5.2.3.0","v5.2.4.0","v5.2.5.0","v5.2.6.0","v5.3.0.0","v5.3.1.0","v5.3.2.0","v5.3.3.0","v5.3.4.0","v5.3.6.0","v5.4.0.0","v5.4.1.0","v5.4.2.0","v5.4.3.0","v5.5.0.0","v5.5.1.0","v6.0.0.0","v6.0.1.0","v6.0.2.0","v6.0.3.0","v6.1.0.0","v6.1.1.0","v6.1.2.0","v6.1.3.0","v6.1.4.0","v6.1.5.0","v6.2.0.0","v6.2.1.0","v6.2.2.0","v6.2.3.0","v6.3.0.0","v6.3.1.0","v6.3.10.0","v6.3.11.0","v6.3.12.0","v6.3.13.0","v6.3.14.0","v6.3.15.0","v6.3.16.0","v6.3.17.0","v6.3.18.0","v6.3.19.0","v6.3.2.0","v6.3.3.0","v6.3.4.0","v6.3.5.0","v6.3.6.0","v6.3.7.0","v6.3.8.0","v6.3.9.0","v7.0.0.0","v7.0.1.0","v7.0.2.0","v7.0.3.0","v7.0.4.0","v7.1.0.0","v7.1.1.0","v7.1.2.0","v7.2.0.0","v7.2.1.0","v7.2.2.0","v7.2.3.0","v7.2.4.0","v7.2.5.0","v7.2.6.0","v7.3.0.0","v7.3.1.0","v7.3.2.0","v8.0","v8.0.1","v8.0.2","v8.1","v8.1.0.1","v8.1.1","v8.1.2","v8.1.3","v8.1.4","v8.1.5","v8.1.6","v8.1.7","v8.1.8","v8.2.0","v8.2.1","v8.2.2","v8.2.3","v8.2.4","v8.2.5","v8.2.6","v8.2.8.1","v8.2.8.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27811.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
