CakePHP through 5.4.3 contains an sql injection vulnerability that allows attackers to inject SQL by supplying unvalidated collation values to StringExpression and IdentifierExpression. Attackers controlling a collation name passed to the constructor or setCollation() can append SQL after the unquoted COLLATE clause, affecting every database driver within the connection's privileges.
