{"apiVersion":"1.0","identifier":"CVE-2026-81728","description":"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->db->query(). 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.","publishedAt":"2026-08-27T20:18:55","lastModifiedAt":"2026-08-28T18:56:49","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81728","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00256,"riskScore":0.83,"affectedProduct":"Dolibarr","affectedVersions":"<24.0.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-81728","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-81728","en":"https://www.redsauce.net/en/cves/CVE-2026-81728","fr":"https://www.redsauce.net/fr/cves/CVE-2026-81728","pt":"https://www.redsauce.net/pt/cves/CVE-2026-81728","de":"https://www.redsauce.net/de/cves/CVE-2026-81728","sk":"https://www.redsauce.net/sk/cves/CVE-2026-81728","el":"https://www.redsauce.net/el/cves/CVE-2026-81728"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-81728"}}
