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-2026-84197 in the wild and no public exploit code.\n\nAffected product: Eclipse Ditto. 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-2026-84197/ (Markdown: https://insights.sbomify.com/CVE-2026-84197/index.md)","id":"CVE-2026-84197","markdown":"https://insights.sbomify.com/CVE-2026-84197/index.md","name":"CVE-2026-84197","record":{"aliases":["GHSA-j7r5-6vmc-cmcc"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse Ditto JS client","requires_auth":"none","summary":"The Node.js client disables TLS certificate validation, allowing attackers to intercept connections and read or modify Ditto Protocol messages.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-300","name":"Channel Accessible by Non-Endpoint"},{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"},{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"In Eclipse Ditto's Node.js JavaScript client, all released versions of @eclipse-ditto/ditto-javascript-client-node from 2.0.0 to 3.9.0 and of its predecessor package @eclipse-ditto/ditto-javascript-client-node_1.0 from 1.0.0 to 2.1.0, the WebSocket transport hard-codes rejectUnauthorized: false when creating the underlying ws WebSocket. Certificate chain and hostname validation are therefore disabled for every wss:// connection, and no builder option, constructor argument or environment variable lets an application turn validation back on.

The Java client, the browser/DOM JavaScript client and the HTTP transport of the Node.js client are not affected.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Security feature bypass in Eclipse Ditto","id":"CVE-2026-84197","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Multiple vulnerabilities affect the Sniffer component as part of IBM Guardium Data Protection","id":"CVE-2026-84198"},"packages":[],"prev":{"headline":"Kyverno before 1.18.0 Server-Side Request Forgery via apiCall","id":"CVE-2026-84196"},"products":["Eclipse Ditto"],"published":"2026-09-08","related":[],"sources":[{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-09","vendors":["Eclipse Foundation"]},"summary":"The Node.js client disables TLS certificate validation, allowing attackers to intercept connections and read or modify Ditto Protocol messages.","url":"https://insights.sbomify.com/CVE-2026-84197/"}
