Upgrade org.apache.tomcat.embed:tomcat-embed-core to version 9.0.123, 10.1.61, 11.0.27 or higher.
Overview
org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.
Affected versions of this package are vulnerable to Incomplete Cleanup via handshake-wrap state handling in the SecureNioChannel component. A TLS client can trigger intermittent TLS 1.3 connection failures by sending traffic that leaves a handshake wrap pending; after the channel wraps application data, its handshake-progress flag remains stale, so subsequent handshake processing throws an I/O error and the connection fails.
