{"id":"CVE-2026-81728","summary":"Dolibarr before 24.0.0 SQL Injection via the CSV and XLSX Import Update Keys","details":"Dolibarr before 24.0.0 contains a SQL injection in its CSV and XLSX import wizard. The wizard reads its update keys with GETPOST('updatekeys', 'array') in htdocs/imports/import.php, which applies only the generic alphanohtml filter: that strips HTML but leaves SQL keywords, comment markers, parentheses, spaces and quotes intact. import_insert() in htdocs/core/modules/import/import_csv.modules.php then iterates the submitted values and builds a filter with $where[] = $key.' = '.$data[$key], having first applied preg_replace('/^.*\\./i', '', $key), an alias strip that does nothing to a value containing no dot. The assembled string is executed through $this-\u003edb-\u003equery(). The injected SELECT resolves the row id that the import then assigns to $lastinsertid, which becomes the WHERE target of a subsequent UPDATE, so a UNION SELECT returning an attacker-chosen integer both exfiltrates arbitrary table content and redirects which row the import overwrites; for category link tables the raw filter array is spliced into that UPDATE directly. The interface offers a fixed list of legitimate column codes but the server never checks the submitted values against it. A user holding the import permission can exploit this. Release 23.0.4 does not carry the fix; the allow-list test was added in 24.0.0.","modified":"2026-08-29T03:45:59.498049999Z","published":"2026-08-27T20:07:33.503Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81728.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81728.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81728"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/dolibarr-before-24.0.0-sql-injection-via-the-csv-and-xlsx-import-update-keys"},{"type":"FIX","url":"https://github.com/Dolibarr/dolibarr/commit/24b1b99c89c79a3fe2d1e83b22dc1810cf0fa6e1"},{"type":"PACKAGE","url":"https://github.com/Dolibarr/dolibarr"},{"type":"ARTICLE","url":"https://github.com/Dolibarr/dolibarr/blob/23.0.4/htdocs/core/modules/import/import_csv.modules.php#L925"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dolibarr/dolibarr","events":[{"introduced":"0"},{"fixed":"769c7db907099643558e77d7002c109cfda919e5"},{"fixed":"24b1b99c89c79a3fe2d1e83b22dc1810cf0fa6e1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"24.0.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["lne_audit_init_20260601","14.0.0","14.0.1","6.0.0-beta","5.0.0-beta","4.0.0-rc","3.8.0-beta","3.7.1","3.7.0","3.6.2","3.6.1","3.6.0","3.6.0-beta","3.6.beta1_20140514","3.6.0-alpha","3.5.beta1_20131120","3.5.beta1_20131106","3.4.beta1_20130502","3.4.beta1_20130429","3.3.beta1_20121221"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-81728.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
