Prior to version 26.1.10, the Trust module stores attacker-controlled certificate authority and certificate refid values and interpolates them into XPath expressions in src/opnsense/mvc/app/models/OPNsense/Trust/FieldTypes/CAsField.php and src/opnsense/mvc/app/models/OPNsense/Trust/FieldTypes/CertificatesField.php. A user with CA Manager or Certificate Manager privileges can submit a crafted refid and repeatedly retrieve the object to obtain a boolean refcount oracle, allowing values in config.xml to be recovered character by character. Exposed values can include password hashes, API credentials, certificate private keys, VPN key material, and high-availability credentials, enabling privilege escalation and compromise of other security domains. This issue is fixed in version 26.1.10.","state":0,"publishedAt":"2026-10-15T15:08:46.374+00:00","modifiedAt":"2026-10-16T17:13:42.903+00:00","affected":[{"ecosystem":"Vendor product","name":"core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"opnsense\",\n                    \"product\": \"core\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 26.1.10\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:L","score":7.1,"severity":"HIGH"}],"references":["https://github.com/opnsense/core/security/advisories/GHSA-xww7-76m6-mh2r","https://github.com/opnsense/core/commit/e2cd067343511252fb0d391a17d82d3ecceece45","https://github.com/opnsense/core/commit/fc2f0d745c17855d2027b192fd4e3fa913e26859"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53582","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53582","identifiers":["CVE-2026-53582"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
