{"id":"CVE-2026-44331","details":"In ProFTPD through 1.3.9a before 7666224, a SQL injection vulnerability in sqltab_fetch_clients_cb() in contrib/mod_wrap2_sql.c allows a remote attacker to inject arbitrary SQL commands via a crafted domain name that is accessed in a reverse DNS lookup. When \"UseReverseDNS on\" is enabled, the attacker-supplied hostname is passed unescaped into SQL queries. The character restrictions of DNS names may affect exploitability.","modified":"2026-06-18T03:57:01.585218059Z","published":"2026-05-05T19:41:06.243Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44331.json","cwe_ids":["CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44331.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44331"},{"type":"REPORT","url":"https://github.com/proftpd/proftpd/issues/2057"},{"type":"FIX","url":"https://github.com/proftpd/proftpd/commit/766622456440fbca33abd7927c523673a11d1ed1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/proftpd/proftpd","events":[{"introduced":"0"},{"fixed":"390b21555268bbc64b66d2dfa7ae40476419b80f"},{"fixed":"766622456440fbca33abd7927c523673a11d1ed1"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.3.9a"}]}}],"versions":["v1.3.9a","v1.3.10rc1","v1.3.9","v1.3.9rc3","v1.3.9rc2","v1.3.9rc1","v1.3.8","v1.3.8rc4","v1.3.8rc3","v1.3.8rc2","v1.3.8rc1","v1.3.7","v1.3.7rc4","v1.3.7rc3","v1.3.7rc2","v1.3.7rc1","v1.3.6","v1.3.6rc4","v1.3.6rc3","v1.3.6rc2","v1.3.6rc1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-44331.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
