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. This issue affects applications that use DefaultRecordSeparatorPolicy or JsonRecordSeparatorPolicy . The default policy ( SimpleRecordSeparatorPolicy ) is not affected.","severity":null,"techs":["spring","java"],"cves":["CVE-2026-47881"],"tags":["security"],"source":{"id":"spring-security","name":"Spring Security Advisories"},"published_at":"2026-08-20T00:00:00.000Z","fetched_at":"2026-10-21T16:17:45.704Z"}
