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-2026-19318 in the wild and no public exploit code.\n\nAffected product: WatchGuard Fireware OS. 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-2026-19318/ (Markdown: https://insights.sbomify.com/CVE-2026-19318/index.md)","id":"CVE-2026-19318","markdown":"https://insights.sbomify.com/CVE-2026-19318/index.md","name":"CVE-2026-19318","record":{"aliases":["GHSA-hj2q-w426-x635"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WatchGuard Fireware OS","requires_auth":"none","summary":"Remote unauthenticated attackers can execute arbitrary code on WatchGuard Fireware OS devices via a stack buffer overflow in the iked process.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"},{"id":"CWE-129","name":"Improper Validation of Array Index"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to execute arbitrary code by sending specially crafted network traffic.","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 Pre-Authentication Stack Buffer Overflow in iked Allows Remote Code Execution","id":"CVE-2026-19318","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":"Power System Integer Overflow","id":"CVE-2026-19321"},"packages":[],"prev":{"headline":"Fireware OS Pre-Authentication Out-of-Bounds Read in iked Allows Denial of Service (DoS)","id":"CVE-2026-19317"},"products":["Fireware OS"],"published":"2026-08-27","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":"total"},"state":"PUBLISHED","updated":"2026-09-03","vendors":["WatchGuard"]},"summary":"Remote unauthenticated attackers can execute arbitrary code on WatchGuard Fireware OS devices via a stack buffer overflow in the iked process.","url":"https://insights.sbomify.com/CVE-2026-19318/"}
