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-2026-43515 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected all versions; fixed in 9.0.118\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected all versions; fixed in 9.0.118\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- org.apache.tomcat.embed:tomcat-embed-core (Maven): affected from 11.0.0-M1; fixed in 11.0.22\n- tomcat (Bitnami): affected from 10.0.0; fixed in 10.1.55, 11.0.22, 9.0.118\n- org.apache.tomcat:tomcat (Maven): affected all versions; fixed in 9.0.118\n- org.apache.tomcat:tomcat (Maven): affected all versions; fixed in 9.0.118\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat:tomcat (Maven): affected from 10.1.0-M1; fixed in 10.1.55\n- org.apache.tomcat:tomcat (Maven): affected from 11.0.0-M1; fixed in 11.0.22\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-2026-43515/ (Markdown: https://insights.sbomify.com/CVE-2026-43515/index.md)","id":"CVE-2026-43515","markdown":"https://insights.sbomify.com/CVE-2026-43515/index.md","name":"CVE-2026-43515","record":{"aliases":["BIT-tomcat-2026-43515","CLEANSTART-2026-SE01248","CLEANSTART-2026-SP62177","CLSA-2026-1781744133","DEBIAN-CVE-2026-43515","GHSA-5m62-pw8w-7w9f","MINI-54xx-gw62-xh9h","MINI-x2hc-4p54-pqpw","MINI-xp5x-24cw-w4w7","ROOT-APP-MAVEN-CVE-2026-43515","UBUNTU-CVE-2026-43515"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can bypass security constraints in Apache Tomcat when multiple method constraints define an HTTP method for the same extension.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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-285","name":"Improper Authorization"}],"description":"Improper Authorization vulnerability when multiple method constraints define an HTTP method for the same extension in Apache Tomcat.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109.\n\nUsers are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-06-19","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-19T11:08:22Z","kind":"github_poc","ref":"https://github.com/covepseng/cve-2026-43515-poc","stars":1,"title":"Exploitability PoC for CVE-2026-43515 (Apache Tomcat constraint bypass)."}],"tier":"poc_unverified"},"has_fix":true,"headline":"Apache Tomcat: Security constraints not correctly applied","id":"CVE-2026-43515","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:tomcat","products":["apache:tomcat"],"type":"missing_authorization","year":"2026"},"n_packages":19,"n_references":1,"next":{"headline":"OpenClaw \u003c 2026.4.12 -
