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...

Since Spring Security SAML decrypts SAML Responses as well as elements of SAML LogoutRequests and LogoutResponses without requiring a valid signature, attackers may be able to craft these SAML payloads and use the Service Provider as a decryption oracle. Affected versions: Spring Security 5.7.0...

CVE-2026-47838

SubjectDnX509PrincipalExtractor does not correctly handle certain malformed X.509 certificate CN values, which can lead to reading the wrong value for the username. In a carefully crafted certificate, this can lead to an attacker impersonating another user. Affected versions: Spring Security 5.7....

CVE-2026-41727

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...
