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-2026-101356/ (Markdown: https://insights.sbomify.com/CVE-2026-101356/index.md)","id":"CVE-2026-101356","markdown":"https://insights.sbomify.com/CVE-2026-101356/index.md","name":"CVE-2026-101356","record":{"aliases":["BIT-tomcat-2026-101356","DEBIAN-CVE-2026-101356","GHSA-w9r8-5j45-v8mg","UBUNTU-CVE-2026-101356"],"analysis":null,"analysis_generated_by":null,"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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Incorrect object recycling and re-use vulnerability in Apache Tomcat affecting HTTP/2 processing of asynchronous servlets can trigger request and/or response mix-up between users.\n\nThis issue affects Apache Tomcat: from 11.0.22 through 11.0.26, from 10.1.55 through 10.1.60, from 9.0.118 through 9.0.122.\n\nUsers are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fixes 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 request/response mix-up after error during async processing","id":"CVE-2026-101356","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Cross-site scripting in SEOPress – AI SEO Plugin \u0026 On-site SEO","id":"CVE-2026-101357"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.123","10.1.61","11.0.27"],"introduced":["9.0.118","10.1.55","11.0.22"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2026-101356"}],"prev":{"headline":"FAST FAC1203R MmtAtePrase _tWlanTask stack-based overflow","id":"CVE-2026-101354"},"products":["Apache Tomcat"],"published":"2026-10-20","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":"2026-10-20","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-101356/"}
