  "details" : [ "Allocation of Resources Without Limits or Throttling vulnerability in Apache Tomcat.\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117.\nOlder, unsupported versions may also be affected.\nUsers are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.", "In Apache Tomcat, no limit was enforced on the request body for WebDAV LOCK or PROPFIND requests which were available to unauthenticated users. This allows a remote attacker to consume excessive resources, leading to Denial of Service (DoS), making the affected system unavailable to legitimate users." ],
