A later anonymous form submission associates that temporary attachment with the newly created submission. When an administrator opens the submission, the component's JavaScript retrieves the stored attachment record and concatenates `file.name` directly into an HTML string. The complete string is assigned to `innerHTML`.","state":0,"publishedAt":"2026-09-29T16:57:36.625+00:00","modifiedAt":"2026-10-01T04:45:23.591+00:00","affected":[{"ecosystem":"Vendor product","name":"com_baforms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageName\": \"com_baforms\",\n                    \"product\": \"Balbooa Forms extension for Joomla\",\n                    \"vendor\": \"balbooa.com\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.0-2.4.3.3\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","score":8.6,"severity":"HIGH"}],"references":["https://www.balbooa.com/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-101127","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101127","identifiers":["CVE-2026-101127"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
