CVE-2022-40830Network attack vector

SQL injection via caller-controlled field names

Published Oct 7, 2022 · Updated Aug 3, 2024

SQL injection in CodeIgniter 3.1.13 and earlier allows remote attackers to alter database queries through a crafted field name. The where_not_in() path passes its caller-supplied key to _where_in(), which concatenates that key into a NOT IN condition while escaping only the values. Reachability requires an application to accept a client-controlled field name; the upstream issue questions whether that developer misuse constitutes a framework flaw, and the CVE is disputed.
