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-2026-8247 in the wild and no public exploit code.\n\nAffected product: Watchguard Fireware. 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-2026-8247/ (Markdown: https://insights.sbomify.com/CVE-2026-8247/index.md)","id":"CVE-2026-8247","markdown":"https://insights.sbomify.com/CVE-2026-8247/index.md","name":"CVE-2026-8247","record":{"aliases":["GHSA-h2w9-p676-66ch"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"WatchGuard Firebox","requires_auth":"none","summary":"An unauthenticated attacker on the local network can execute arbitrary code via an out-of-bounds write in WatchGuard Firebox admd.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[{"product":"fireware","vendor":"watchguard"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"An Out-of-bounds Write vulnerability in WatchGuard Fireware OS may allow an unauthenticated attacker on the same local network segment to execute arbitrary code.\n\nThis vulnerability affects Fireware OS 11.0 up to and including 11.12.4_Update1, 12.0 up to and including 12.12 and 2025.1 up to and including 2026.2.","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":"WatchGuard Firebox admd Out of Bounds Write Vulnerability","id":"CVE-2026-8247","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"watchguard:fireware","products":["watchguard:fireware"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Open5GS SMF npcf-handler.c update_authorized_pcc_rule_and_qos denial of service","id":"CVE-2026-8248"},"packages":[],"prev":{"headline":"Concrete CMS 9.5.0 and below is vulnerable to Reflected XSS in Legacy Pagination via HTML attribute injection","id":"CVE-2026-8245"},"products":["Fireware OS"],"published":"2026-07-02","related":[{"cvss_score":9.8,"headline":"WatchGuard Firebox and XTM Appliances Arbitrary Code Execution","id":"CVE-2022-26318","kev_date_added":"2022-03-25","published":"2022-03-04"},{"cvss_score":9.3,"headline":"WatchGuard Firebox Out of Bounds Write","id":"CVE-2025-14733","kev_date_added":"2025-12-19","published":"2025-12-19"},{"cvss_score":9.3,"headline":"WatchGuard Firebox Out-of-Bounds Write","id":"CVE-2025-9242","kev_date_added":"2025-11-12","published":"2025-09-17"},{"cvss_score":8.8,"headline":"WatchGuard Firebox and XTM Privilege Escalation","id":"CVE-2022-23176","kev_date_added":"2022-04-11","published":"2022-02-24"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2022-31789","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2013-6021","kev_date_added":null,"published":"2013-10-19"},{"cvss_score":9.2,"headline":"Fireware OS Code Injection in BOVPN Over TLS Client Allows Remote Code Execution","id":"CVE-2026-86131","kev_date_added":null,"published":"2026-09-29"}],"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":"total"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["WatchGuard"]},"summary":"An unauthenticated attacker on the local network can execute arbitrary code via an out-of-bounds write in WatchGuard Firebox admd.","url":"https://insights.sbomify.com/CVE-2026-8247/"}
