CVE-2022-40828Network attack vector

SQL injection via concatenated query field names

Published Oct 7, 2022 · Updated Apr 9, 2025

SQL injection in CodeIgniter 3.1.13 and earlier allows remote attackers to alter database queries through attacker-controlled field names. The or_where_not_in() path passes its field-name argument into _wh_in(), which concatenates it into the IN clause while escaping only values. The upstream issue states that exploitation requires application code to accept query fields from a client, and the CVE record notes that multiple third parties dispute the claim.
