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-2026-126258 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\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-2026-126258/ (Markdown: https://insights.sbomify.com/CVE-2026-126258/index.md)","id":"CVE-2026-126258","markdown":"https://insights.sbomify.com/CVE-2026-126258/index.md","name":"CVE-2026-126258","record":{"aliases":["GHSA-jx7c-cqh8-2v65"],"analysis":{"component_type":"network_device","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"firewall OS","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated attackers with wad port access can crash FortiOS proxy or ZTNA sessions via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"memory_corruption","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"fortinet","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability in Fortinet FortiOS 8.0.0, FortiOS 7.6.7 may allow an unauthenticated attacker with wad port access to crash proxy or ZTNA sessions via crafted HTTP or HTTPS 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":"Memory corruption in FortiOS","id":"CVE-2026-126258","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in FortiOS","id":"CVE-2026-126259"},"nickname":null,"packages":[],"prev":{"headline":"Hardcoded credentials in FortiAuthenticator","id":"CVE-2026-126257"},"products":["FortiOS"],"published":"2026-11-11","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-11-12","vendors":["Fortinet"]},"summary":"Unauthenticated attackers with wad port access can crash FortiOS proxy or ZTNA sessions via crafted HTTP requests.","url":"https://insights.sbomify.com/CVE-2026-126258/"}
