A new configuration section and capabilities around transforming source headers and payload to desired mappings on the target headers and payload has been added. The mappings are expressed in the connector configuration using an expression language based on Spring Expression Language (SpEL).

Various string and number functions are available to transform values to the desired target format, for example join, mask, abs, and many more.

This release supports JSON payloads only. Future releases will add other content formats such as XML. If your source and target payload is not JSON, you cannot map or transform the payload and it is passed through as is. However, you can still do header transforms and smart topic dynamic producer destinations.

This is a new capability and is not compatible with the "transform-headers" and "transform-payload" sections of the configuration available prior to this release. The "transform-headers" and "transform-payload" sections continue to work but are now deprecated and will be removed in a future release.

Existing connector configurations that rely on the legacy transform sections should not use the new transform capabilities. The legacy and new transform sections cannot be used together.

Messages are now processed in batches, with transactions possible on the consumer side, producer side, or both. Refer to the documentation for the benefits and tradeoffs of batching and transactions. Note that the default batch size is 255, and that the {{solace.connector.process}} and {{solace.connector.error.process}} metrics now apply to batches instead of individual messages. To get metrics on individual messages you can use the {{solace.connector.publish.ack}} metric.

Migrate to Latest Connector Framework Using Spring Boot 3.3 Release

Support in the Solace source binder for consuming from a Durable Topic Endpoint (in addition to queues). Also added support for selectors on both Queues and Durable Topic Endpoints.

Added support (internal) for NACK handling of messages not processed due to error. This is a breaking change regarding supported PubSub+ broker versions. The connectors now require a 10.2.1+ broker version to operate.

The connector now includes all required IBM MQ Client sub-dependencies. Users only need to include the IBM MQ Client jar version that is supported by their installed connector version. For the supported IBM MQ Client version, refer to the latest upgrade information in this release note. Including additional IBM MQ Client sub-dependencies is not supported.

Note: This version supports IBM MQ Client 9.4.1.1.

JMS consumer bindings no longer map {{jms_destination}} and {{jms_replyTo}} headers. As a result, these headers are no longer accessible for use in transform-header expressions. If your configuration includes default workflow transform-header expressions that nullify these headers, you can now remove those expressions.

Fixed the issue in reading user property having value of type byte[] or ByteArray while mapping Solace Consumer message to Spring message.

StreamMessages are not supported by this version of the connector due to an issue within the Spring Framework. Solace is working with Spring to address this issue and will reinstate StreamMessage support in a future release. Attempted processing of StreamMessages will result in an “UnsupportedOperationException” in the connector.

In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL function can cause memory to be written beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the result buffer, and thus malloc may not allocate enough memory.

A bug in PSL validation logic in Apache HttpClient 5.4.x disables domain checks, affecting cookie management and host name verification. Discovered by the Apache HttpClient team. Fixed in the 5.4.3 release

Netty, an asynchronous, event-driven network application framework, has a vulnerability starting in version 4.1.91.Final and prior to version 4.1.118.Final. When a special crafted packet is received via SslHandler it doesn\'t correctly handle validation of such a packet in all cases which can lead to a native crash. Version 4.1.118.Final contains a patch. As workaround its possible to either disable the usage of the native SSLEngine or change the code manually.

Spring Security 6.4.0 through 6.4.3 may not correctly locate method security annotations on parameterized types or methods. This may cause an authorization bypass. Your application may be affected by this if the following are true:

BCryptPasswordEncoder.matches(CharSequence,String) will incorrectly return true for passwords larger than 72 characters as long as the first 72 characters are the same.

Netty, an asynchronous, event-driven network application framework, has a vulnerability in versions up to and including 4.1.118.Final. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. Commit d1fbda62d3a47835d3fb35db8bd42ecc205a5386 contains an updated fix.

A security issue was found in Netplex Json-smart 2.5.0 through 2.5.1. When loading a specially crafted JSON input, containing a large number of ’{’, a stack exhaustion can be trigger, which could allow an attacker to cause a Denial of Service (DoS). This issue exists because of an incomplete fix for CVE-2023-1370.

### Summary When parsing unknown fields in the Protobuf Java Lite and Full library, a maliciously crafted message can cause a StackOverflow error and lead to a program crash. Reporter: Alexis Challande, Trail of Bits Ecosystem Security Team Affected versions: This issue affects all versions of both the Java full and lite Protobuf runtimes, as well as Protobuf for Kotlin and JRuby, which themselves use the Java Protobuf runtime. ### Severity [CVE-2024-7254](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-7254) **High** CVSS4.0 Score 8.7 (NOTE: there may be a delay in publication) This is a potential Denial of Service. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker. ### Proof of Concept For reproduction details, please refer to the unit tests (Protobuf Java [LiteTest](https://github.com/protocolbuffers/protobuf/blob/a037f28ff81ee45ebe008c64ab632bf5372242ce/java/lite/src/test/java/com/google/protobuf/LiteTest.java) and [CodedInputStreamTest](https://github.com/protocolbuffers/protobuf/blob/a037f28ff81ee45ebe008c64ab632bf5372242ce/java/core/src/test/java/com/google/protobuf/CodedInputStreamTest.java)) that identify the specific inputs that exercise this parsing weakness. ### Remediation and Mit

Missing Authorization When Using @AuthorizeReturnObject in Spring Security 6.3.0 and 6.3.1 allows attacker to render security annotations inaffective.

Spring Framework is vulnerable DoS via conditional HTTP request. Applications that parse ETags from "If-Match" or "If-None-Match" request headers are vulnerable to Denial of Service attack. All versions before 5.3.38, 6.0.23 and 6.1.12 are affected.

A use-after-free vulnerability was discovered in xasprintf function in xfuncs_printf.c:344 in BusyBox v.1.36.1.

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. This vulnerability is fixed in 4.1.115.

Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect infinite timeout which allowed connections to remain open which should have been closed.

The usage of String.toLowerCase() and String.toUpperCase() has some Locale dependent exceptions that could potentially result in authorization rules not working properly.

BouncyCastle before version 1.78 is vulnerable to timing side-channel attacks against RSA decryption (both PKCS#1v1.5 and OAEP).

An issue was discovered in ECCurve.java and ECCurve.cs in Bouncy Castle Java (BC Java) before 1.78, BC Java LTS before 2.73.6, BC-FJA before 1.0.2.5, and BC C# .Net before 2.3.1. Importing an EC certificate with crafted F2m parameters can lead to excessive CPU consumption during the evaluation of the curve parameters.

An issue was discovered in the FIPS Java API of Bouncy Castle BC-FJA before 1.0.2.4. Changes to the JVM garbage collector in Java 13 and later trigger an issue in the BC-FJA FIPS modules where it is possible for temporary keys used by the module to be zeroed out while still in use by the module, resulting in errors or potential information loss. NOTE: FIPS compliant users are unaffected because the FIPS certification is only for Java 7, 8, and 11.

In Spring Security, versions 5.7.x prior to 5.7.12, 5.8.x prior to 5.8.11, versions 6.0.x prior to 6.0.9, versions 6.1.x prior to 6.1.8, versions 6.2.x prior to 6.2.3, an application is possible vulnerable to broken access control when it directly uses the AuthenticatedVoter#vote passing a null Authentication parameter.

libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.

Applications that use UriComponentsBuilder to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a open redirect attack or to a SSRF attack if the URL is used after passing validation checks. This is the same as CVE-2024-22259 and CVE-2024-22243, but with different input.
