Multiple POST parameters including graph-left, graph-right, time-period, resolution, start-date, end-date, start-time, end-time, graph-type, invert, and refresh-interval are concatenated and written to the global pfSense XML configuration without sanitization, then echoed unsanitized into a JavaScript string context on page render. Because the setting is stored in the global configuration, the payload executes in the browser of every user who visits the Status: Monitoring page.","state":0,"publishedAt":"2026-09-03T14:19:43.18+00:00","modifiedAt":"2026-10-01T19:19:22.567+00:00","affected":[{"ecosystem":"https://github.com/getformwork/formwork","name":"pfSense Plus","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Netgate\",\n                    \"product\": \"pfSense Plus\",\n                    \"collectionURL\": \"https://github.com/getformwork/formwork\",\n                    \"packageURL\": \"pkg:github/getformwork/formwork\",\n                    \"repo\": \"https://github.com/getformwork/formwork\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"26.07\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"pfSense CE","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"Netgate\",\n                    \"product\": \"pfSense CE\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.9.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.1,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://docs.netgate.com/downloads/pfSense-SA-26_09.packages.asc","https://docs.netgate.com/pfsense/en/latest/releases/26-07.html","https://docs.netgate.com/pfsense/en/latest/releases/2-9-0.html","https://www.vulncheck.com/advisories/pfsense-plus-ce-stored-xss-via-status-monitoring-php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56126","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56126","identifiers":["CVE-2026-56126"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
