Data disclosure via object-valued MySQL WHERE clauses
Published Dec 19, 2022 · Updated Aug 6, 2024
SQL injection in Knex Knex.js through 2.3.0 allows remote attackers to read unintended MySQL rows via crafted WHERE values. The MySQL query compiler accepts object or array values in basic and raw WHERE bindings, then emits their contents as SQL that changes the intended predicate. Exploitation requires a consuming application to pass attacker-controlled structured values into a Knex WHERE clause while using MySQL, allowing database filters to be bypassed.
