Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Apache Tomcat caused by processing the transfer-encoding header for an HTTP/1.0 request may allow an attacker to cause one request from another user to fail when Tomcat is located behind a reverse proxy.
This issue affects Apache Tomcat: from 11.0.0 through 11.0.25, from 10.1.0 through 10.1.59, from 9.0.47 through 9.0.121.
