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-2026-78437 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomcat (Bitnami): affected from 9.0.116; fixed in 9.0.122, 10.1.60, 11.0.26\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-2026-78437/ (Markdown: https://insights.sbomify.com/CVE-2026-78437/index.md)","id":"CVE-2026-78437","markdown":"https://insights.sbomify.com/CVE-2026-78437/index.md","name":"CVE-2026-78437","record":{"aliases":["BIT-tomcat-2026-78437","DEBIAN-CVE-2026-78437","GHSA-hvg5-8g86-xm44","MINI-p8hh-f3g5-cqqp","MINI-qq53-899p-6m39","MINI-w697-q898-mprq","UBUNTU-CVE-2026-78437"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"A malformed HTTP/2 request in Apache Tomcat can cause other users' requests to fail, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"Incomplete cleanup vulnerability in Apache Tomcat allows a malformed request to potentially (depends on timing) cause one request from another user to fail.\n\nThis issue affects Apache Tomcat: from 11.0.19 through 11.0.25, from 10.1.53 through 10.1.59, from 9.0.116 through 9.0.121.\n\nUsers are recommended to upgrade to version 11.0.26, 10.1.60 or 9.0.122, which fix the issue.","ecosystems":["Bitnami"],"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: HTTP/2 DoS via malformed request","id":"CVE-2026-78437","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"W3 Total Cache \u003c= 2.10.5 - Unauthenticated Stored Cross-Site Scripting via LazyLoad Background Mutator","id":"CVE-2026-78438"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.122","10.1.60","11.0.26"],"introduced":["9.0.116","10.1.53","11.0.19"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2026-78437"}],"prev":{"headline":"Faveo Helpdesk Logo SettingsController.php unlink path traversal","id":"CVE-2026-78435"},"products":["Apache Tomcat"],"published":"2026-09-23","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-23","vendors":["Apache Software Foundation"]},"summary":"A malformed HTTP/2 request in Apache Tomcat can cause other users' requests to fail, leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2026-78437/"}
