CVE-2026-47881

Description

Spring Batch's FlatFileItemReader supports files where a single logical record spans multiple physical lines — for example, a CSV field that contains embedded newlines wrapped in quotes. A specially crafted input file could exploit the way the reader assembles those multi-line records to consume excessive CPU time and memory, causing the batch job to stall or run out of memory.
