For a subset of unlikely rewrite rule configurations, it was possible \nfor a specially crafted request to bypass some rewrite rules. If those \nrewrite rules effectively enforced security constraints, those \nconstraints could be bypassed.\n\nThis issue affects Apache Tomcat: from 11.0.0 through 11.0.5, from 10.1.0 through 10.1.39, from 9.0.0 through 9.0.102.\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions \nmay also be affected.\n\n\nUsers are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.","affected":[{"package":{"name":"tomcat","ecosystem":"Bitnami","purl":"pkg:bitnami/tomcat"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.104"},{"introduced":"10.0.0"},{"fixed":"10.1.40"},{"introduced":"11.0.0"},{"fixed":"11.0.6"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tomcat/BIT-tomcat-2025-31651.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}],"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2025/04/28/3"},{"type":"ADVISORY","url":"https://lists.apache.org/list.html?announce@tomcat.apache.org"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-31651"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/07/msg00009.html"}],"database_specific":{"cpes":["cpe:2.3:a:apache:tomcat:*:*:*:*:*:maven:*:*"],"severity":"Critical"}}
