Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-81858 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-2026-81858/ (Markdown: https://insights.sbomify.com/CVE-2026-81858/index.md)","id":"CVE-2026-81858","markdown":"https://insights.sbomify.com/CVE-2026-81858/index.md","name":"CVE-2026-81858","record":{"aliases":["GHSA-wf64-vjxh-jr77"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM i OS","requires_auth":"low_privilege","summary":"A remote authenticated attacker can cause a denial of service and read sensitive information via an out-of-bounds read in the File Server.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"i","vendor":"ibm"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"IBM i 7.3, 7.4, 7.5, and 7.6 could allow a remote authenticated attacker to cause a denial of service and obtain information due to an out-of-bounds read in the File Server.","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 A Denial of Service Vulnerability in Host Servers","id":"CVE-2026-81858","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:i","products":["ibm:i"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Multiple security vulnerabilities are addressed with IBM Cloud Pak for Business Automation iFixes for August 2026.","id":"CVE-2026-81859"},"packages":[],"prev":{"headline":"Terminal escape sequence injection in Hex via unneutralized server-supplied output","id":"CVE-2026-81856"},"products":["i"],"published":"2026-10-12","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":"2026-10-13","vendors":["IBM"]},"summary":"A remote authenticated attacker can cause a denial of service and read sensitive information via an out-of-bounds read in the File Server.","url":"https://insights.sbomify.com/CVE-2026-81858/"}
