Spring Boot 3.0.0-M1 is now available

On behalf of the team and everyone who has contributed, I’m happy to announce that Spring Boot 3.0.0-M1 has been released and is now available from https://repo.spring.io/milestone.

This milestone starts our exciting journey to the next generation of the Spring Framework and raises our baseline from Java 8 to Java 17. We are planning to release a new milestone of Spring Boot 3.0 every two months. M2 should arrive on March 24 and we are planning on a GA release in late November.

If you are trying an existing application with Spring Boot 3.0 you’ll need to be aware that we’ve migrated all Java EE APIs to their equivalent Jakarta EE variant. For most users, this means you’ll need to replace any javax imports with jakarta. For example, javax.servlet.Filter would be replaced with jakarta.servlet.Filter.

Log4J2 Vulnerability and Spring Boot

Updates: Since this blog post has been published, a new logback 1.2.9 version has been published. While this fixes a security issue, prerequisites for exploits are very different as they “requires write access to logback’s configuration file”.
Log4J also released a new 2.17.0 version with fixes for CVE-2021-45046 and CVE-2021-45105.
Spring Boot 2.5.8 and 2.6.2 haven been released and provide dependency management for logback 1.2.9 and Log4J 2.17.0.
Log4J 2.17.1 contains a fix for CVE-2021-44832

As you may have seen in the news, a new zero-day exploit has been reported against the popular Log4J2 library which can allow an attacker to remotely execute code. The vulnerability has been reported with CVE-2021-44228 against the log4j-core jar and has been fixed in Log4J v2.15.0.
