@shivacharan0551 please consider searching the issue tracker before opening an issue. We already upgraded in 2.4.x and already indicated in that issue why we won't upgrade to a new feature release in a maintenance release of Spring Boot.

Please reach out to the Undertow team to ask them to backport. Alternatively, you can upgrade as explained in the comment I've referenced.
