Descriptions

In spring framework versions prior to 5.2.24 release+ ,5.3.27+ and 6.0.8+ , it is possible for a user to provide a specially crafted SpEL expression that may cause a denial-of-service (DoS) condition.

A flaw was found in Spring Framework. Certain versions of Spring Framework's Expression Language were not restricting the size of Spring Expressions. This could allow an attacker to craft a malicious Spring Expression to cause a denial of service on the server.

This release of Camel for Spring Boot 3.20.1 serves as a replacement for Camel for Spring Boot 3.18.3 and includes bug fixes and enhancements, which are documented in the Release Notes document linked in the References. The purpose of this text-only errata is to inform you about the security issues fixed. Issues addressed include bypass, code execution, cross site scripting, denial of service, man-in-the-middle, memory exhaustion, resource exhaustion, and traversal vulnerabilities.
