  - CVE-2023-42795: When recycling various internal objects, including the request and the response,

  recycling process leading to information leaking from the current request/response to the next.

  - CVE-2023-44487: HTTP/2 rapid reset attack

  - CVE-2023-45648: A specially crafted, invalid trailer header could cause Tomcat to treat a single
  request as multiple requests leading to the possibility of request smuggling when behind a reverse
  proxy.");
