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-2026-4942 in the wild and no public exploit code.\n\nAffected product: Ibm I. 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-2026-4942/ (Markdown: https://insights.sbomify.com/CVE-2026-4942/index.md)","id":"CVE-2026-4942","markdown":"https://insights.sbomify.com/CVE-2026-4942/index.md","name":"CVE-2026-4942","record":{"aliases":["GHSA-cffx-9q2g-r6hp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM i OS","requires_auth":"none","summary":"Remote attackers can downgrade TLS protocol versions on IBM i systems, bypassing security configurations intended to disable weaker protocols.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"i","vendor":"ibm"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-757","name":"Selection of Less-Secure Algorithm During Negotiation"}],"description":"IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to send a specifically crafted message and downgrade the Transport Layer Security (TLS) protocol to a version disabled in the server configuration.","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":"IBM i is Affected by Algorithm Downgrade in Transport Layer Security []","id":"CVE-2026-4942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:i","products":["ibm:i"],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded trust_remote_code=True in vllm-project/vllm Bypasses User Security Control","id":"CVE-2026-4944"},"packages":[],"prev":{"headline":"Incorrect Authorization in IBM Verify Identity Access and IBM Security Verify Access","id":"CVE-2026-4938"},"products":["i"],"published":"2026-07-17","related":[{"cvss_score":9.9,"headline":"IBM i is Affected By An Improper Control of Code Generation Vulnerability in HTTP Server Administration GUI","id":"CVE-2026-96119","kev_date_added":null,"published":"2026-10-12"},{"cvss_score":9.9,"headline":"IBM i is Affected By Remote Code Execution Vulnerability []","id":"CVE-2026-16860","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.8,"headline":"IBM i is Affected By Multiple Vulnerabilities in the Debug Server","id":"CVE-2026-17083","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.8,"headline":"IBM i is Affected By Remote Code Execution Vulnerability in Line Printer Daemon []","id":"CVE-2026-17218","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.6,"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-17276","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":8.9,"headline":"IBM i Is Affected By Multiple Vulnerabilities in IBM Java SDK and IBM Java Runtime","id":"CVE-2026-18193","kev_date_added":null,"published":"2026-08-13"},{"cvss_score":8.9,"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-18099","kev_date_added":null,"published":"2026-08-12"}],"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":"2026-07-20","vendors":["IBM"]},"summary":"Remote attackers can downgrade TLS protocol versions on IBM i systems, bypassing security configurations intended to disable weaker protocols.","url":"https://insights.sbomify.com/CVE-2026-4942/"}
