Descriptions

In Spring Framework versions 6.0.0 - 6.0.6, 5.3.0 - 5.3.25, 5.2.0.RELEASE - 5.2.22.RELEASE, and older unsupported versions, it is possible for a user to provide a specially crafted SpEL expression that may cause a denial-of-service (DoS) condition.

A flaw found was found in Spring Framework. This flaw allows a malicious user to use a specially crafted SpEL expression that causes a denial of service (DoS).

Red Hat support for Spring Boot provides an application platform that reduces the complexity of developing and operating applications for OpenShift as a containerized platform. This release of Red Hat support for Spring Boot 2.7.13 serves as a replacement for Red Hat support for Spring Boot 2.7.12, and includes security, bug fixes and enhancements. For more information, see the release notes linked in the References section. Issues addressed include bypass, code execution, denial of service, and deserialization vulnerabilities.
