An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53434 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat:tomcat-util (Maven): affected from 10.1.0-M7; fixed in 10.1.56\n- org.apache.tomcat:tomcat-util (Maven): affected from 10.1.0-M7; fixed in 10.1.56\n- org.apache.tomcat:tomcat-util (Maven): affected from 11.0.0-M1; fixed in 11.0.23\n- org.apache.tomcat:tomcat-util (Maven): affected from 11.0.0-M1; fixed in 11.0.23\n- org.apache.tomcat:tomcat-util (Maven): affected from 9.0.83; fixed in 9.0.119\n- org.apache.tomcat:tomcat-util (Maven): affected from 9.0.83; fixed in 9.0.119\n- tomcat (Bitnami): affected all versions; fixed in 9.0.101, 10.1.37, 11.0.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-53434/ (Markdown: https://insights.sbomify.com/CVE-2026-53434/index.md)","id":"CVE-2026-53434","markdown":"https://insights.sbomify.com/CVE-2026-53434/index.md","name":"CVE-2026-53434","record":{"aliases":["BIT-tomcat-2026-53434","DEBIAN-CVE-2026-53434","GHSA-4x29-79gh-6v8q","ROOT-APP-MAVEN-CVE-2026-53434","UBUNTU-CVE-2026-53434"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Tomcat","requires_auth":"none","summary":"An attacker can bypass certificate revocation checks in Apache Tomcat FFM connectors due to improper error handling in CRL configuration.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tomcat","vendor":"apache"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-390","name":"Detection of Error Condition Without Action"}],"description":"Detection of Error Condition Without Action vulnerability in Apache Tomcat when configuring CRLs for a FFM based connector.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.22, from 10.1.0-M7 through 10.1.55, from 9.0.83 through 9.0.118.\n\nUsers are recommended to upgrade to version 11.0.23, 10.1.56 or 9.0.119, which fixes the issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache Tomcat: Invalid CRL configuration doesn't trigger failure for FFM Connector","id":"CVE-2026-53434","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:tomcat","products":["apache:tomcat"],"type":"security_feature_bypass","year":"2026"},"n_packages":7,"n_references":1,"next":{"headline":"Jenkins arbitrary type deserialization from attacker-controlled config.xml allows remote code execution and user impersonation","id":"CVE-2026-53435"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.101","10.1.37","11.0.5"],"introduced":["0","10.0.0","11.0.0"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2026-53434"},{"ecosystem":"Maven","fixed":["10.1.56"],"introduced":["10.1.0-M7"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":null,"source":"GHSA-4x29-79gh-6v8q"},{"ecosystem":"Maven","fixed":["10.1.56"],"introduced":["10.1.0-M7"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":"pkg:maven/org.apache.tomcat/tomcat-util","source":"GHSA-4x29-79gh-6v8q"},{"ecosystem":"Maven","fixed":["11.0.23"],"introduced":["11.0.0-M1"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":null,"source":"GHSA-4x29-79gh-6v8q"},{"ecosystem":"Maven","fixed":["11.0.23"],"introduced":["11.0.0-M1"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":"pkg:maven/org.apache.tomcat/tomcat-util","source":"GHSA-4x29-79gh-6v8q"},{"ecosystem":"Maven","fixed":["9.0.119"],"introduced":["9.0.83"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":null,"source":"GHSA-4x29-79gh-6v8q"},{"ecosystem":"Maven","fixed":["9.0.119"],"introduced":["9.0.83"],"last_affected":[],"package":"org.apache.tomcat:tomcat-util","purl":"pkg:maven/org.apache.tomcat/tomcat-util","source":"GHSA-4x29-79gh-6v8q"}],"prev":{"headline":"Denial of Service in fzf","id":"CVE-2026-53433"},"products":["Apache Tomcat"],"published":"2026-06-29","related":[{"cvss_score":10,"headline":"Apache Tomcat Path Equivalence","id":"CVE-2025-24813","kev_date_added":"2025-04-01","published":"2025-03-10"},{"cvss_score":9.8,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2016-8735","kev_date_added":"2023-05-12","published":"2017-04-06"},{"cvss_score":8.1,"headline":"Apache Tomcat Remote Code Execution","id":"CVE-2017-12617","kev_date_added":"2022-03-25","published":"2017-10-03"},{"cvss_score":8.1,"headline":"Apache Tomcat on Windows Remote Code Execution","id":"CVE-2017-12615","kev_date_added":"2022-03-25","published":"2017-09-19"},{"cvss_score":7.5,"headline":"Apache Tomcat Missing Encryption of Sensitive Data","id":"CVE-2026-34486","kev_date_added":"2026-08-04","published":"2026-04-09"},{"cvss_score":9.8,"headline":"Apache Tomcat: HTTP/2 no-authority bypass of strict SNI validation -
