Logback 1.5.35 rejects Unicode escape sequences in <if> condition attributes to block a bypass of the existing prohibition on the new operator. The announcement says version 1.5.37 provides the full fix.
The 'condition' attribute in <if> elements now rejects unicode escape sequences (\u and \U). This closes a bypass of the existing prohibition on the new operator in Janino-evaluated conditions.
