That path was likely not to be protected by the same security constraints as the expected path, allowing those security constraints to be bypassed.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from 9.0.0.M1 through 9.0.105.\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. Other, older, EOL versions \nmay also be affected.\n\n\nUsers are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-288"],"references":["https://lists.apache.org/thread/m66cytbfrty9k7dc4cg6tl1czhsnbywk","http://www.openwall.com/lists/oss-security/2025/06/16/2","https://lists.debian.org/debian-lts-announce/2025/07/msg00009.html"],"products":["apache:tomcat"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-49125","score":0.03437,"percentile":0.88966,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wc4r-xq3c-5cf3","url":"https://osv.dev/vulnerability/GHSA-wc4r-xq3c-5cf3","summary":"Apache Tomcat - Security constraint bypass for pre/post-resources","modified":"2026-09-10T03:50:26.000004953Z","packages":[{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina","ranges":[">=11.0.0-M1 <11.0.8"],"fixed":["11.0.8"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina","ranges":[">=10.1.0-M1 <10.1.42"],"fixed":["10.1.42"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina","ranges":[">=9.0.0.M1 <9.0.106"],"fixed":["9.0.106"]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=11.0.0-M1 <11.0.8"],"fixed":["11.0.8"]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=10.1.0-M1 <10.1.42"],"fixed":["10.1.42"]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=9.0.0.M1 <9.0.106"],"fixed":["9.0.106"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","purl":"pkg:maven/org.apache.tomcat/tomcat-catalina","ranges":[">=8.5.0 <=8.5.100"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=8.5.0 <=8.5.100"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
