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-2026-49364 in the wild and no public exploit code.\n\nAffected product: Apache ActiveMQ Artemis. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-49364/ (Markdown: https://insights.sbomify.com/CVE-2026-49364/index.md)","id":"CVE-2026-49364","markdown":"https://insights.sbomify.com/CVE-2026-49364/index.md","name":"CVE-2026-49364","record":{"aliases":["GHSA-fjwp-v5xg-5q39"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Message Broker","requires_auth":"none","summary":"An unauthenticated attacker can capture cluster administrative credentials during the initial handshake, potentially leading to unauthorized access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"artemis","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-306","name":"Missing Authentication for Critical Functionality"}],"description":"An unauthenticated network-adjacent attacker can leverage discovery to capture cluster administrative credentials during the initial cluster connection handshake.\n\nThis issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0.\n\nUsers are recommended to upgrade to version 2.57.0, which fixes the issue.","ecosystems":[],"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":"Information disclosure in Apache ActiveMQ Artemis","id":"CVE-2026-49364","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Camel-Netty-HTTP: The muteException consumer option defaulted to false, so a processing error returned the full Java stack trace in the HTTP response body","id":"CVE-2026-49365"},"packages":[],"prev":{"headline":"Information disclosure in Apache ActiveMQ Artemis","id":"CVE-2026-49363"},"products":["Apache ActiveMQ Artemis","Apache Artemis"],"published":"2026-09-10","related":[{"cvss_score":9.8,"headline":"Apache Artemis, Apache ActiveMQ Artemis: Missing authentication on CORE protocol session reattachment","id":"CVE-2026-57967","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":9.3,"headline":"Apache Artemis, Apache ActiveMQ Artemis: Auth bypass for Core downstream federation","id":"CVE-2026-27446","kev_date_added":null,"published":"2026-03-04"},{"cvss_score":9.1,"headline":"Missing authorization in Apache ActiveMQ Artemis","id":"CVE-2026-67593","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.8,"headline":"Apache ActiveMQ Artemis: Authenticated users could perform RCE via Jolokia MBeans","id":"CVE-2023-50780","kev_date_added":null,"published":"2024-10-14"},{"cvss_score":7.5,"headline":"Missing authorization in Apache ActiveMQ Artemis","id":"CVE-2026-49362","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":7.5,"headline":"Information disclosure in Apache ActiveMQ Artemis","id":"CVE-2026-49363","kev_date_added":null,"published":"2026-09-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["Apache Software Foundation"]},"summary":"An unauthenticated attacker can capture cluster administrative credentials during the initial handshake, potentially leading to unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-49364/"}
