CVE-2026-47881

EUVD-2026-66844

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.
Spring Batch 6.0.0 - 6.0.4
Spring Batch 5.2.0 - 5.2.6
Spring Batch 4.3.0 - 4.3.13

Common Weakness Enumeration

CWE-400 - Uncontrolled Resource Consumption
