CVE-2026-47881 (GCVE-0-2026-47881)

Vulnerability from cvelistv5 – Published: 2026-08-27 05:20 – Updated: 2026-08-27 05:21

Title

Denial of Service in Spring Batch FlatFileItemReader via Malformed Input File

Summary

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

Severity

5.9 (Medium)
