Prior to version 26.1.11, src/www/system_advanced_admin.php reads certificate records into $a_cert but omits that array from legacy_html_escape_form_data() before rendering each certificate descr value in the SSL Certificate selector. The certificate description accepts HTML metacharacters, allowing a user with the page-system-certmanager privilege to store markup that executes when another user opens System Settings Administration. This issue is fixed in version 26.1.11.","state":0,"publishedAt":"2026-10-15T15:20:15.232+00:00","modifiedAt":"2026-10-15T18:36:57.734+00:00","affected":[{"ecosystem":"Vendor product","name":"core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"opnsense\",\n                    \"product\": \"core\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.1.11\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:L/A:N","score":5.2,"severity":"MEDIUM"}],"references":["https://github.com/opnsense/core/security/advisories/GHSA-8pgr-x852-qx4j","https://github.com/opnsense/core/commit/9d0a590e9c49f4374a5539929b366123f63bc9eb","https://github.com/opnsense/core/commit/adcb02f8f68071e636bf9660b2cb8d0229f34674","https://hackerask.com/posts/opnsense"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-58394","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-58394","identifiers":["CVE-2026-58394"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
