Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-75880 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-2026-75880/ (Markdown: https://insights.sbomify.com/CVE-2026-75880/index.md)","id":"CVE-2026-75880","markdown":"https://insights.sbomify.com/CVE-2026-75880/index.md","name":"CVE-2026-75880","record":{"aliases":["GHSA-c9m2-388v-p4rq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Message broker","requires_auth":"low_privilege","summary":"An authenticated attacker can cause denial of service in Apache ActiveMQ Artemis by using crafted message selectors that exhaust broker threads.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"artemis","vendor":"apache"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"An authenticated client could attach a consumer with a selector containing crafted wildcard usage that results in excessive evaluation during message delivery attempts, occupying a shared broker thread and leading to denial of service.\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 this 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":"Apache Artemis, Apache ActiveMQ Artemis: Message selector wildcard handling could lead to denial of service","id":"CVE-2026-75880","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM Maximo Application Suite - IoT Component Denial of Service","id":"CVE-2026-75881"},"packages":[],"prev":{"headline":"IBM Sterling File Gateway is Vulnerable to Authentication Bypass","id":"CVE-2026-75878"},"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":"Information disclosure in Apache ActiveMQ Artemis","id":"CVE-2026-49364","kev_date_added":null,"published":"2026-09-10"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Apache Software Foundation"]},"summary":"An authenticated attacker can cause denial of service in Apache ActiveMQ Artemis by using crafted message selectors that exhaust broker threads.","url":"https://insights.sbomify.com/CVE-2026-75880/"}
