The version of Apache Tomcat installed on the remote host is 9.0.0-M1 prior to 9.0.116, 10.1.0-M1 prior to 10.1.53 or 11.0.0-M1 prior to 11.0.20. It is, therefore, affected by multiple vulnerabilities :

 - The EncryptInterceptor used CBC by default which is vulnerable to a padding Oracle attack. (CVE-2026-29146)

 - The validation of SNI name and host name did not take account of possible differences in case allowing the strict SNI checks to be bypassed. This is an incomplete fix for CVE-2025-66614. (CVE-2026-32990)

 - CLIENT_CERT authentication did not fail OCSP checks as expected for some scenarios when soft fail was disabled. (CVE-2026-29145)

 - The addition of the ability to configure TLS 1.3 cipher suites did not preserve the order of the configured cipher suites and ciphers. (CVE-2026-29129)

 - When a Tomcat node in a cluster with the LoadBalancerDrainingValve was in the disabled (draining) state, a specially crafted URL could be used to trigger a redirect to a URI of the attacker's choice. (CVE-2026-25854)

 - Tomcat did not validate the contents of HTTP/1.1 chunk extensions. This enabled a request smuggling attack if a reverse proxy in front of Tomcat allowed CRLF sequences in an otherwise valid chunk extension. (CVE-2026-24880)

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
