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-2026-79677 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tomcat (Bitnami): affected all versions; fixed in 9.0.45, 10.1.60, 11.0.26, 9.0.122\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-2026-79677/ (Markdown: https://insights.sbomify.com/CVE-2026-79677/index.md)","id":"CVE-2026-79677","markdown":"https://insights.sbomify.com/CVE-2026-79677/index.md","name":"CVE-2026-79677","record":{"aliases":["BIT-tomcat-2026-79677","DEBIAN-CVE-2026-79677","GHSA-r5gx-4gq8-822g","MINI-hgpm-j82r-g9xf","MINI-m754-5mr9-hfvh","MINI-mppw-6c2q-x35h","UBUNTU-CVE-2026-79677"],"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":"Apache Tomcat suffers from a denial of service vulnerability due to lost asynchronous write timeouts in WebSocket connections.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"},{"id":"CWE-1025","name":"Comparison Using Wrong Factors"}],"description":"Missing release of resource after effective lifetime, Comparison using wrong factors vulnerability in Apache Tomcat allows a denial of service as a result of lost time outs for asynchronous WebSocket writes.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.25, from 10.1.0-M1 through 10.1.59, from 9.0.0.M1 through 9.0.121.\n\nThe following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.43 through 7.0.109. Other unsupported versions may also be affected.\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: WebSocket DoS due to lost asynchronous write timeout","id":"CVE-2026-79677","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":"Code injection in Red Hat Enterprise Linux 10","id":"CVE-2026-79678"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.45","10.1.60","11.0.26","9.0.122"],"introduced":["0","10.1.0","11.0.0","9.0.0"],"last_affected":[],"package":"tomcat","purl":"pkg:bitnami/tomcat","source":"BIT-tomcat-2026-79677"}],"prev":{"headline":"NLTK before 3.10.3 Path Traversal via Symlink Bypass","id":"CVE-2026-79676"},"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":"Apache Tomcat suffers from a denial of service vulnerability due to lost asynchronous write timeouts in WebSocket connections.","url":"https://insights.sbomify.com/CVE-2026-79677/"}
