EUVD-2026-66850

JsonKafkaHeaderMapper and DefaultKafkaHeaderMapper include java.net in their default trusted packages list. When these mappers are used — which is the default configuration for all @KafkaListener consumers — an external Kafka producer can inject a java.net.InetAddress type via the...

Improper Check for Unusual or Exceptional Conditions

Overview Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions via the DeadLetterPublishingRecovererFactory. An attacker can cause repeated failures and stall partition consumption by attaching a malformed retrytopic-original-timestamp header suc...

Improper Validation Of User-Controlled Retry Header Value

Spring Kafka is vulnerable to improper validation of user-controlled retry header value. The vulnerability is due to insufficient validation of the retrytopic-attempts header, which allows an attacker to craft an out-of-range retry attempt count and cause the retry topic router to incorrectly...

CVE-2026-41731

A flaw was found in the spring-kafka component. A remote attacker, by supplying crafted header values, could exploit a vulnerability in JsonKafkaHeaderMapper and DefaultKafkaHeaderMapper that incorrectly matched type headers against trusted packages. This issue, combined with Jackson's default be...

CVE-2026-41726

A flaw was found in spring-kafka. When an application uses the DelegatingDeserializer, a malicious producer can exploit this vulnerability by sending records with unique, random spring.kafka.serialization.selector header values. This can cause the consumer's memory heap to grow without limits,...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the JsonKafkaHeaderMapper or the deprecated DefaultKafkaHeaderMapper functions. An attacker can achieve arbitrary code execution by supplying crafted header values that trigger deserialization of...

Improper Validation of Specified Quantity in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input in the retrytopic-attempts header. An attacker can manipulate retry routing and backoff behavior by sending crafted headers with out-of-range attempt counts. Remediation Upgrade...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the DelegatingDeserializer function. An attacker can exhaust system memory by sending records with unique, random spring.kafka.serialization.selector header values, leading to...

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...
