An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-126247 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 FortiAuthenticator. 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-2026-126247/ (Markdown: https://insights.sbomify.com/CVE-2026-126247/index.md)","id":"CVE-2026-126247","markdown":"https://insights.sbomify.com/CVE-2026-126247/index.md","name":"CVE-2026-126247","record":{"aliases":["GHSA-9r63-2p2h-xm89"],"analysis":{"component_type":"network_device","exploitable_when_present":false,"fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"authentication appliance","requires_auth":"high_privilege","requires_specific_call":false,"summary":"An authenticated privileged attacker can exploit a format string flaw via HTTP requests to execute unauthorized code on FortiAuthenticator.","user_interaction":"not_required","vuln_class":"memory_corruption","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"fortinet","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"A use of externally-controlled format string vulnerability in Fortinet FortiAuthenticator 8.0.0 through 8.0.3, FortiAuthenticator 6.6.0 through 6.6.10 may allow an authenticated privileged attacker to execute unauthorized code or commands via http 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 FortiAuthenticator","id":"CVE-2026-126247","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":"Information disclosure in FortiAuthenticator","id":"CVE-2026-126248"},"nickname":null,"packages":[],"prev":{"headline":"Null dereference in FortiAuthenticator","id":"CVE-2026-126246"},"products":["FortiAuthenticator"],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-11-12","vendors":["Fortinet"]},"summary":"An authenticated privileged attacker can exploit a format string flaw via HTTP requests to execute unauthorized code on FortiAuthenticator.","url":"https://insights.sbomify.com/CVE-2026-126247/"}
