NewCVE-2026-47881 (opens in a new tab)How to fix?
Upgrade org.springframework.batch:spring-batch-infrastructure to version 6.0.5 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the FlatFileItemReader when handling specially crafted input files that exploit the way multi-line records are assembled. An attacker can cause excessive CPU and memory consumption by providing a malformed file, potentially leading to application stalls or resource exhaustion.
Note: This is only exploitable if either DefaultRecordSeparatorPolicy or JsonRecordSeparatorPolicy is used; the default SimpleRecordSeparatorPolicy is not affected.
Workaround
This vulnerability can be mitigated by adding an application-level check to reject files above a safe size threshold before they are opened by the reader, or by switching to SimpleRecordSeparatorPolicy if multi-line record support is not required.
