• Maven org.apache.tomcat:tomcat: >= 10.1.0-M1, < 10.1.0-M6 → fixed in 10.1.0-M6 • Maven org.apache.tomcat:tomcat: >= 10.0.0-M1, < 10.0.12 → fixed in 10.0.12 • Maven org.apache.tomcat:tomcat: >= 9.0.40, < 9.0.54 → fixed in 9.0.54 • Maven org.apache.tomcat:tomcat: >= 8.5.60, < 8.5.72 → fixed in 8.5.72

The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.
