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-2026-86104 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-2026-86104/ (Markdown: https://insights.sbomify.com/CVE-2026-86104/index.md)","id":"CVE-2026-86104","markdown":"https://insights.sbomify.com/CVE-2026-86104/index.md","name":"CVE-2026-86104","record":{"aliases":["GHSA-44q2-m4gj-p5w4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Fireware OS","requires_auth":"none","summary":"Remote unauthenticated attackers can cause denial of service in WatchGuard Fireware OS by sending crafted requests to the login process.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[{"product":"fireware","vendor":"watchguard"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-409","name":"Improper Handling of Highly Compressed Data (Data Amplification)"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"An uncontrolled resource consumption vulnerability in the Fireware OS login process (wgagent) allows a remote, unauthenticated attacker to cause a denial of service by sending a specially crafted 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 Resource Exhaustion in Login Process Allows Denial of Service","id":"CVE-2026-86104","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"watchguard:fireware","products":["watchguard:fireware"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Fireware OS Improper Authorization in Access Portal Reverse Proxy","id":"CVE-2026-86105"},"packages":[],"prev":{"headline":"WatchGuard AP Command Injection in Internal Management API Allows Command Execution","id":"CVE-2026-86102"},"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["WatchGuard"]},"summary":"Remote unauthenticated attackers can cause denial of service in WatchGuard Fireware OS by sending crafted requests to the login process.","url":"https://insights.sbomify.com/CVE-2026-86104/"}
