It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-62439 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-2025-62439/ (Markdown: https://insights.sbomify.com/CVE-2025-62439/index.md)","id":"CVE-2025-62439","markdown":"https://insights.sbomify.com/CVE-2025-62439/index.md","name":"CVE-2025-62439","record":{"aliases":["GHSA-76xc-486m-c526"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Fortinet FortiOS","requires_auth":"low_privilege","summary":"Authenticated users with FSSO knowledge can bypass access controls to reach protected network resources via crafted requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[],"cvss":{"score":3.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N/E:P/RL:X/RC:R","version":"3.1"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"An Improper Verification of Source of a Communication Channel vulnerability [CWE-940] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.4, FortiOS 7.4.0 through 7.4.9, FortiOS 7.2 all versions, FortiOS 7.0 all versions may allow an authenticated user with knowledge of FSSO policy configurations to gain unauthorized access to protected network resources via crafted requests.","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":"Auth bypass in FortiOS","id":"CVE-2025-62439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Not used","id":"CVE-2025-62440"},"packages":[],"prev":{"headline":"ClipBucket v5 stored XSS via video/photo fields","id":"CVE-2025-62430"},"products":["FortiOS"],"published":"2026-02-10","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":"2026-05-12","vendors":["Fortinet"]},"summary":"Authenticated users with FSSO knowledge can bypass access controls to reach protected network resources via crafted requests.","url":"https://insights.sbomify.com/CVE-2025-62439/"}
