The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process.\r\n\r\nSecurity Fix(es):\n\nImproper Input Validation vulnerability.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from 9.0.0-M1 through 9.0.112.\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected.\nTomcat did not validate that the host name provided via the SNI \nextension was the same as the host name provided in the HTTP host header \nfield. If Tomcat was configured with more than one virtual host and the \nTLS configuration for one of those hosts did not require client \ncertificate authentication but another one did, it was possible for a \nclient to bypass the client certificate authentication by sending \ndifferent host names in the SNI extension and the HTTP host header field.\n\n\n\nThe vulnerability only applies if client certificate authentication is \nonly enforced at the Connector. It does not apply if client certificate \nauthentication is enforced at the web application.\n\n\nUsers are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue.(CVE-2025-66614)\n\nImproper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the GET method. If a security constraint was configured to allow HEAD requests to a URI but deny GET requests, the user could bypass that constraint on GET requests by sending a (specification invalid) HEAD request using HTTP/0.9.(CVE-2026-24733)\n\nImproper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat.\n\nWhen using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification or freshness checks on the OCSP response which could allow certificate revocation to be bypassed.\n\nThis issue affects Apache Tomcat Native:  from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat: from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114.\n\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: from 1.1.23 through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected.\n\nApache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue.\n\nApache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which fix the issue.(CVE-2026-24734)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-24.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2403sp3"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2403.noarch.rpm","tomcat-help-9.0.115-1.oe2403.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403.noarch.rpm","tomcat-9.0.115-1.oe2403sp1.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp1.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp1.noarch.rpm","tomcat-9.0.115-1.oe2403sp2.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp2.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp2.noarch.rpm","tomcat-9.0.115-1.oe2403sp3.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp3.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp3.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2403.src.rpm","tomcat-9.0.115-1.oe2403sp1.src.rpm","tomcat-9.0.115-1.oe2403sp2.src.rpm","tomcat-9.0.115-1.oe2403sp3.src.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2403sp1"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2403sp1.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp1.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp1.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2403sp1.src.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP2","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-24.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2403sp2"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2403sp2.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp2.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp2.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2403sp2.src.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2403sp3"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2403sp3.noarch.rpm","tomcat-help-9.0.115-1.oe2403sp3.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2403sp3.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2403sp3.src.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2003sp4"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2003sp4.noarch.rpm","tomcat-help-9.0.115-1.oe2003sp4.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2003sp4.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2003sp4.src.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"tomcat","purl":"pkg:rpm/openEuler/tomcat&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.115-1.oe2203sp4"}]}],"ecosystem_specific":{"noarch":["tomcat-9.0.115-1.oe2203sp4.noarch.rpm","tomcat-help-9.0.115-1.oe2203sp4.noarch.rpm","tomcat-jsvc-9.0.115-1.oe2203sp4.noarch.rpm"],"src":["tomcat-9.0.115-1.oe2203sp4.src.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1651"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66614"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24733"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24734"}],"database_specific":{"severity":"Critical"}}
