CVE-2026-41731 (GCVE-0-2026-41731)

Vulnerability from cvelistv5 – Published: 2026-06-09 23:49 – Updated: 2026-07-15 00:58

Title

In Spring for Apache Kafka, overly broad trusted-package matching in header mappers exposes JDK classes to deserialization

Summary

JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Combined with Jackson's default bean deserialization, a producer could supply crafted header values that caused the consumer to deserialize arbitrary JDK types. Affected versions: Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11.
