The EmbeddedHeadersJsonMessageMapper defaults to an overly permissive header parsing posture in its constructor. When decodeNativeFormat processes raw byte payloads, it deserializes embedded JSON headers into a plain Map and constructs a GenericMessage with MutableMessageHeaders without sanitizing or filtering untrusted header names by default. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

A single ScriptEngine instance is reused for every message on a script-backed channel. For JSR-223 engines that report THREADING=null (not thread-safe, e.g. the Kotlin kts engine), concurrent message processing can corrupt engine-internal state, potentially leaking one message's payload/headers bindings into another message's script evaluation or throwing spurious exceptions. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

When a container-level ErrorHandler is configured (the mitigation for finding 221000), each delivery whose processing throws still permanently consumes one link credit. After initialCredits (default 100) failing messages the receiver's credit reaches zero and the broker stops delivering, leaving the listener silently stalled while isRunning() remains true. Spring AMQP 4.1.0

RedisChatMemoryRepository.findByMetadata() builds RediSearch tag and text queries from caller-supplied metadata values without applying RediSearchUtil.escape(), unlike get(), clear(), and findByTimeRange() in the same class which do escape their inputs. An application that passes user-controlled values to findByMetadata() on a tag-typed metadata field allows an attacker to inject RediSearch syntax (e.g. x} | ) that breaks out of the tag clause and matches all indexed chat messages across every conversation in the index. Spring AI 2.0.0

DeadLetterPublishingRecovererFactory reads the retrytopic-original-timestamp header from an inbound ConsumerRecord and passes its raw bytes directly to new BigInteger(header.value()) with no length or format validation.

Potential for logging sensitive data in Spring Cloud Function Azure. Spring Cloud Function 5.0.0 - 5.0.3 Spring Cloud Function 4.3.0 - 4.3.4 Spring Cloud Function 4.2.0 - 4.2.7

ResourceCacheService.getCacheName() builds the on-disk filename by appending the URI fragment verbatim, without stripping path separators or .. sequences, and passes the result to new File(resourceParentFolder, newFileName) before writing the downloaded bytes there. Spring AI 2.0.0 Spring AI 1.1.0 - 1.1.8 Spring AI 1.0.9 and earlier

Unless the application explicitly raises smbMinVersion, the jCIFS client will negotiate down to SMB1/CIFS, which lacks mandatory signing/encryption and is vulnerable to NTLM relay and content-tampering MITM. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12

Spring MVC and WebFlux applications that obtain a data-binding Errors instance with HTML escaping enabled and then render field errors using the no-argument Errors.getFieldErrors() or Errors.getFieldError() accessors are vulnerable to arbitrary HTML/JavaScript code injection, potentially resulting in a reflected cross-site scripting (XSS) vulnerability. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

Spring Security's InetAddressMatchers utility provides matchInternal() and matchExternal() builders for constructing an InetAddressMatcher that classifies a given IP address as belonging to an internal (private) or external (public) network. Spring Security 7.1.0

Several components in Spring Security compare security-sensitive values using standard string equality (String.equals()) rather than a constant-time comparison. Because String.equals() returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the number of leading characters that match the expected value. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6 Spring Security 6.5.0 - 6.5.11 Spring Security 6.4.0 - 6.4.18 Spring Security 5.8.0 - 5.8.27 Spring Security 5.7.0 - 5.7.25

Applications using Spring Framework's FreeMarker integration may be vulnerable to a path traversal attack when a controller returns a view name derived from untrusted input and FreeMarker is configured to resolve templates through SpringTemplateLoader.

Any application shipping logs to RabbitMQ over TLS via the Log4j2 appender, relying on the documented default, is exposed to man-in-the-middle interception of every log event. Spring AMQP 4.1.0 Spring AMQP 4.0.0 - 4.0.4 Spring AMQP 3.2.0 - 3.2.12 Spring AMQP 2.4.18 and earlier

A Spring MVC application that uses UrlFileNameViewController that is mapped with an end-of-path, and does not have a configured prefix is vulnerable to an open redirect. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

UrlHandlerFilter can be vulnerable to an open redirect when configured with very broadly matching patterns. The issue applies to the filter variants in both Spring MVC and Spring WebFlux. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19

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 springjsonheadertypes message header. Spring for Apache Kafka 4.1.0 Spring for Apache Kafka 4.0.0 - 4.0.6 Spring for Apache Kafka 3.0.0 - 3.3.16 Spring for Apache Kafka 2.9.0 - 2.9.14 Spring for Apache Kafka 2.8.12 and earlier

A single hostile AMQP message can terminate the entire consumer JVM (System.exit(99)), not just the listener thread — full availability loss for every workload co-located in that process. Spring AMQP 4.1.0 Spring AMQP 4.0.0 - 4.0.4 Spring AMQP 3.2.0 - 3.2.12 Spring AMQP 2.4.18 and earlier

The UnZipTransformer does not limit decompressed entry size or entry count when processing archives. Consequently, an attacker can send a zip archive that can exhaust JVM heap memory, causing a denial-of-service outage. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12

RFC6587SyslogDeserializer, used by the Spring Integration syslog TCP inbound adapter to decode RFC 6587 / RFC 5424 frames, trusts the sender-supplied octet count of an octet-counted frame and allocates a byte array of exactly that size with no upper bound. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

Spring Integration's JSON to object conversion uses the jsonTypeId header to choose the deserialization target type, and resolves that header value to a class with ClassUtils.forName and no type/package allow-list.
