An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18145 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-2026-18145/ (Markdown: https://insights.sbomify.com/CVE-2026-18145/index.md)","id":"CVE-2026-18145","markdown":"https://insights.sbomify.com/CVE-2026-18145/index.md","name":"CVE-2026-18145","record":{"aliases":["GHSA-6g2x-6j83-r28p"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Firewall OS","requires_auth":"high_privilege","summary":"An authenticated administrator can trigger a stack-based buffer overflow in spamd to execute arbitrary code or crash the service on WatchGuard Fireware OS.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[{"product":"fireware","vendor":"watchguard"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability in the spamBlocker (spamd) service of WatchGuard Fireware OS allows an authenticated attacker with administrator privileges to crash the service or potentially execute arbitrary code by sending a specially crafted management request.","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":"Fireware OS Stack-based Buffer Overflow in spamd Allows Remote Code Execution","id":"CVE-2026-18145","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":1,"next":{"headline":"Fluent Forms \u003c= 6.2.11 - Unauthenticated Stored Cross-Site Scripting via Notification Smartcode Values","id":"CVE-2026-18146"},"packages":[],"prev":{"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-18144"},"products":["Fireware OS"],"published":"2026-09-29","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":"2026-10-01","vendors":["WatchGuard"]},"summary":"An authenticated administrator can trigger a stack-based buffer overflow in spamd to execute arbitrary code or crash the service on WatchGuard Fireware OS.","url":"https://insights.sbomify.com/CVE-2026-18145/"}
