Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-59840 in the wild and no public exploit code.\n\nAffected product: Fortinet Fortios. 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-2026-59840/ (Markdown: https://insights.sbomify.com/CVE-2026-59840/index.md)","id":"CVE-2026-59840","markdown":"https://insights.sbomify.com/CVE-2026-59840/index.md","name":"CVE-2026-59840","record":{"aliases":["GHSA-r538-x648-7vg8"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet network security","requires_auth":"low_privilege","summary":"A buffer over-read in Fortinet FortiOS and FortiProxy allows attackers to disclose sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"A buffer over-read vulnerability in Fortinet FortiOS 7.6.0 through 7.6.3, FortiOS 7.4.0 through 7.4.8, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiOS 6.4 all versions, FortiProxy 7.6.0 through 7.6.5, FortiProxy 7.4.0 through 7.4.13, FortiProxy 7.2 all versions, FortiProxy 7.0 all versions may allow attacker to information disclosure via \u003cinsert attack vector here\u003e","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":"Information disclosure in FortiOS","id":"CVE-2026-59840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortios","products":["fortinet:fortios","fortinet:fortiproxy"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in FortiSIEMWindowsAgent","id":"CVE-2026-59841"},"packages":[],"prev":{"headline":"Path traversal in FortiOS","id":"CVE-2026-59839"},"products":["FortiOS","FortiPAM","FortiProxy","FortiSwitchManager"],"published":"2026-07-14","related":[{"cvss_score":9.8,"headline":"Fortinet Multiple Products Format String","id":"CVE-2024-23113","kev_date_added":"2024-10-09","published":"2024-02-15"},{"cvss_score":9.8,"headline":"Fortinet Multiple Products Authentication Bypass","id":"CVE-2022-40684","kev_date_added":"2022-10-11","published":"2022-10-18"},{"cvss_score":9.6,"headline":"Fortinet FortiOS and FortiProxy Authentication Bypass","id":"CVE-2024-55591","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":9.6,"headline":"Fortinet FortiOS Out-of-Bound Write","id":"CVE-2024-21762","kev_date_added":"2024-02-09","published":"2024-02-09"},{"cvss_score":9.3,"headline":"Fortinet FortiOS Heap-Based Buffer Overflow","id":"CVE-2022-42475","kev_date_added":"2022-12-13","published":"2023-01-02"},{"cvss_score":9.2,"headline":"Fortinet FortiOS and FortiProxy SSL-VPN Heap-Based Buffer Overflow","id":"CVE-2023-27997","kev_date_added":"2023-06-13","published":"2023-06-13"},{"cvss_score":9.1,"headline":"Fortinet Multiple Products Improper Verification of Cryptographic Signature","id":"CVE-2025-59718","kev_date_added":"2025-12-16","published":"2025-12-09"}],"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":"2026-10-15","vendors":["Fortinet"]},"summary":"A buffer over-read in Fortinet FortiOS and FortiProxy allows attackers to disclose sensitive information.","url":"https://insights.sbomify.com/CVE-2026-59840/"}
