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`.","categories":["Applications & CMS"],"product":"Balbooa Forms extension for Joomla","vendor":"balbooa.com","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101127","source_modified_at":"2026-10-01T04:45:23.591Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Balbooa Forms extension for Joomla","vendor":"balbooa.com","versions":[{"status":"affected","version":"1.0.0-2.4.3.3"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0033,"percentile":0.24879,"score_date":"2026-10-23"},"published_at":"2026-09-29T16:57:36.625Z","modified_at":"2026-10-01T04:45:23.591Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101127","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T04:45:23.591Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101127","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.balbooa.com/","tags":["product"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-30T19:50:17.214559Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-01T04:45:23.591Z","content_hash":"568f6f143035c9a057f0fcbf15cf6ff892ffaa1eff678a6dc8a2a418315d24ce"}}
