CVE-2023-46589 Apache Tomcat - Request Smuggling
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected:
Apache Tomcat 11.0.0-M1 to 11.0.0-M10

of request smuggling when behind a reverse proxy.
Mitigation:

mitigations:
- Upgrade to Apache Tomcat 11.0.0-M11 or later
- Upgrade to Apache Tomcat 10.1.16 or later
