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-2026-56846 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1\n- node-min (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1\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-2026-56846/ (Markdown: https://insights.sbomify.com/CVE-2026-56846/index.md)","id":"CVE-2026-56846","markdown":"https://insights.sbomify.com/CVE-2026-56846/index.md","name":"CVE-2026-56846","record":{"aliases":["ALPINE-CVE-2026-56846","BELL-CVE-2026-56846","BIT-node-2026-56846","BIT-node-min-2026-56846","DEBIAN-CVE-2026-56846","ECHO-49f1-be71-d1b8","GHSA-frc8-j9wv-2348","MINI-636j-xw36-38mr","MINI-73hx-g6q9-5c6r","MINI-789q-p3jf-6xwg","MINI-gxqw-qqwg-vqvw","MINI-hxq3-25m2-qfr9","MINI-qcph-gq9w-gxm3","UBUNTU-CVE-2026-56846"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js runtime","requires_auth":"none","summary":"Remote attackers can exhaust server memory via HTTP/2 header manipulation, causing denial of service in Node.js applications.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A flaw in Node.js HTTP/2 handling can cause HTTP/2 retained header blocks evade maxSessionMemory and enable remote memory exhaustion.\r\n\r\nThis vulnerability affects Node.js **24.x** and **22.x**.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-23T23:43:36Z","kind":"github_poc","ref":"https://github.com/CompleteTech-Security/node-cve-2026-56846-check","stars":0,"title":"Offline Node.js evidence checker for CVE-2026-56846: HTTP/2 retained header memory exhaustion.
