As a result, a visitor who knows the identifier of a company record from the public directory can submit a modified update request for that record directly and overwrite its data, without the application ever confirming that the visitor owns it.","published":"2026-08-25T09:17:35.133","modified":"2026-08-25T09:17:35.133","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-ext-sa-2026-020"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-25T09:17:35.133"}}
