EUVD-2026-35908

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...

GHSA-XVFQ-4Q6Q-GXX7 In Spring for Apache Kafka, unbounded delegate cache keyed on user-controlled, potentially malicious selector header

When an application opts into DelegatingDeserializer, a producer can grow the consumer's heap without bound by sending records with unique random spring.kafka.serialization.selector header values, eventually causing GC thrash and OutOfMemoryError. Affected versions: Spring for Apache Kafka 4.0.0...

EUVD-2026-35904

Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them. A producer could send a record with a crafted retrytopic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the...

GHSA-XQ69-5H5V-X9X4 In Spring for Apache Kafka, overly broad trusted-package matching in header mappers exposes JDK classes to deserialization

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...

Spring for Apache Kafka: Improper Validation of Retry Topic Header Values Leads to Retry Sequence Manipulation

Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them. A producer could send a record with a crafted retrytopic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the...

CVE-2026-45541 ESF-IDF: Remote Null Pointer Dereference in WebSocket Server

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.2.6, 5.3.5, 5.4.4, 5.5.4, and 6.0, a NULL-pointer dereference exists in the WebSocket subprotocol-negotiation path of the esphttpserver component. While parsing the client-supplied Sec-WebSocket-Protocol request...
