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-2026-50734 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- activemq (Bitnami): affected all versions; fixed in 5.19.8, 6.2.7\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-2026-50734/ (Markdown: https://insights.sbomify.com/CVE-2026-50734/index.md)","id":"CVE-2026-50734","markdown":"https://insights.sbomify.com/CVE-2026-50734/index.md","name":"CVE-2026-50734","record":{"aliases":["BIT-activemq-2026-50734","DEBIAN-CVE-2026-50734","GHSA-7259-vf48-52q3","MINI-qf5w-ghhr-wqxv","MINI-qfch-72r9-9pc2","MINI-xpqf-5fc2-vhg7","MINI-xprh-jg3p-c8mf","UBUNTU-CVE-2026-50734"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache ActiveMQ broker","requires_auth":"none","summary":"Unauthenticated attackers can crash the Apache ActiveMQ broker by sending a crafted frame with an excessive size value during pre-authentication negotiation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"activemq","vendor":"apache"}],"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-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ Client, Apache ActiveMQ, Apache ActiveMQ All.\n\nAn unauthenticated network attacker can cause a broker DoS by sending a crafted WireFormatInfo frame with a malicious large size value.
