AV:N/AC:L/Au:S/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions WildFly versions up to 21.0.0.Final

Description A memory leak flaw was found in WildFly where the host-controller tries to reconnect in a loop, generating new connections that are not properly closed while unable to connect to the domain-controller. This allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this issue is to system availability.

Recommendations For versions up to 21.0.0.Final, update to a version later than 21.0.0.Final to resolve the issue. As a temporary workaround, consider restricting the host-controller's ability to reconnect in a loop to minimize the risk of exploitation.
