CVE-2022-40829Network attack vector

SQL injection via client-controlled field names

Published Oct 7, 2022 · Updated Aug 3, 2024

Disputed SQL injection in CodeIgniter 3.1.13 and earlier allows remote attackers to alter database queries through a client-controlled field name. The or_like() path delegates to _like(), which interpolates the supplied field key into a LIKE condition while separately escaping only the match value. Exposure requires application code to pass a client-controlled field name into or_like(); multiple third parties dispute that this constitutes a framework vulnerability.
