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-2026-86350 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomcat (Bitnami): affected from 9.0.118; 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-2026-86350/ (Markdown: https://insights.sbomify.com/CVE-2026-86350/index.md)","id":"CVE-2026-86350","markdown":"https://insights.sbomify.com/CVE-2026-86350/index.md","name":"CVE-2026-86350","record":{"aliases":["BIT-tomcat-2026-86350","DEBIAN-CVE-2026-86350","GHSA-6ff5-mwrj-376m","MINI-3j98-cpmc-m3xw","MINI-7gxq-q4x9-fv9h","MINI-rpfm-wwhq-525v","UBUNTU-CVE-2026-86350"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Tomcat","requires_auth":"none","summary":"Attackers can exploit HTTP/2 request smuggling to cause header mix-ups, potentially bypassing security controls or accessing sensitive data.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"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-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Inconsistent interpretation of HTTP/2 requests ('HTTP Request/Response smuggling') vulnerability in Apache Tomcat caused by a regression in fix for CVE-2026-41293 can trigger request header mix-up.\n\nThis issue affects Apache Tomcat: from 11.0.22 through 11.0.25, from 10.1.55 through 10.1.59, from 9.0.118 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":"2026-09-25","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-25T21:58:58Z","kind":"github_poc","ref":"https://github.com/abraxas/CVE-2026-86350","stars":1,"title":"CVE-2026-86350 - Apache Tomcat - Critical 9.1 - Unauthenticated GET /header.jsp - HTTP/2 Request Header Mix-up (Request Smuggling)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Apache Tomcat: Regression in fix for CVE-2026-41293 can trigger request header mix-up","id":"CVE-2026-86350","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"other","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"MISP User Homepage Validation Allows Authenticated Open Redirect via Protocol-Relative URL","id":"CVE-2026-86351"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.122","10.1.60","11.0.26"],"introduced":["9.0.118","10.1.55","11.0.22"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2026-86350"}],"prev":{"headline":"Mattermost Server Algorithmic DoS via Unbounded Markdown Block Nesting","id":"CVE-2026-86349"},"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-23","vendors":["Apache Software Foundation"]},"summary":"Attackers can exploit HTTP/2 request smuggling to cause header mix-ups, potentially bypassing security controls or accessing sensitive data.","url":"https://insights.sbomify.com/CVE-2026-86350/"}
