spring-batch-infrastructureTL;DR
spring-batch-infrastructure FlatFileItemReader can assemble a single logical record from many physical lines. A crafted file can force excessive CPU and memory while joining quoted or JSON multi-line records. SimpleRecordSeparatorPolicy, the default, is not affected. The patch bounds multi-line record assembly.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and FlatFileItemReader uses DefaultRecordSeparatorPolicy or JsonRecordSeparatorPolicy.
