An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-18251 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-2026-18251/ (Markdown: https://insights.sbomify.com/CVE-2026-18251/index.md)","id":"CVE-2026-18251","markdown":"https://insights.sbomify.com/CVE-2026-18251/index.md","name":"CVE-2026-18251","record":{"aliases":["GHSA-c6mc-4w4v-q86x"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM i OS","requires_auth":"none","summary":"Remote attackers can obtain sensitive information from IBM i Navigator and Digital Certificate Manager due to improper WebSocket origin validation.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-1385","name":"Missing Origin Validation in WebSockets"}],"description":"IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to obtain sensitive information due to improper validation of the WebSocket origin.","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 Multiple Vulnerabilities in Navigator for i and Digital Certificate Manager for i.","id":"CVE-2026-18251","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Inclusion of Functionality from Untrusted Control Sphere in GitLab","id":"CVE-2026-18252"},"packages":[],"prev":{"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-18250"},"products":["i"],"published":"2026-09-14","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":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["IBM"]},"summary":"Remote attackers can obtain sensitive information from IBM i Navigator and Digital Certificate Manager due to improper WebSocket origin validation.","url":"https://insights.sbomify.com/CVE-2026-18251/"}
