CVE-2026-47881
Last modified
CVE-2026-47881 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
