A vulnerability in the JsonMapObjectReaderWriter of Apache CXF allows an attacker to submit malformed JSON to a web service, which results in the thread getting stuck in an infinite loop, consuming CPU indefinitely. This issue affects Apache CXF versions prior to 3.4.4; Apache CXF versions prior to 3.3.11.

Apache CXF is vulnerable to a denial of service, caused by improper validation of requesturi parameter by the OAuth 2 authorization service. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition on the authorization server.
