CVE-2026-41855 Details
Description
In an untrusted JMS environment, org.springframework.jms.support.converter.MappingJackson2MessageConverter and org.springframework.jms.support.converter.JacksonJsonMessageConverter allow arbitrary class instantiation, which can lead to unauthorized actions via gadget class deserialization. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.
A vulnerability exists in the Spring Framework within the Jackson JMS message converters, specifically in versions 7.0.0 through 7.0.7, 6.2.0 through 6.2.18, 6.1.0 through 6.1.27, and 5.3.0 through 5.3.48. In an untrusted JMS environment, these converters permit arbitrary class instantiation, potentially leading to unauthorized actions through gadget class deserialization.
Users in a trusted JMS environment do not need to take any action. For those in an untrusted JMS environment, it is recommended to upgrade to the fixed version and limit authorized packages for deserialization using the new 'setTrustedPackages' methods. The fixed versions are 7.0.8, 6.2.19, 6.1.28, and 5.3.49.
