An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-13371 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-2026-13371/ (Markdown: https://insights.sbomify.com/CVE-2026-13371/index.md)","id":"CVE-2026-13371","markdown":"https://insights.sbomify.com/CVE-2026-13371/index.md","name":"CVE-2026-13371","record":{"aliases":["GHSA-hprc-6hj7-jj8j"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WatchGuard Firebox","requires_auth":"high_privilege","summary":"An authenticated administrator can cause a denial of service in WatchGuard Firebox management by sending crafted data to an unsafe deserialization endpoint.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[{"product":"fireware","vendor":"watchguard"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"An authenticated administrator can trigger a denial-of-service condition in the Fireware Management Web UI by sending malformed or crafted data to the put_data endpoint, which performs unsafe deserialization of the attacker-supplied input.","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 Management Web UI Denial of Service via Unsafe Deserialization","id":"CVE-2026-13371","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"watchguard:fireware","products":["watchguard:fireware"],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Code injection in Remote Desktop Manager","id":"CVE-2026-13372"},"packages":[],"prev":{"headline":"Path traversal in Ninja Forms - File Uploads","id":"CVE-2026-13369"},"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":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["WatchGuard"]},"summary":"An authenticated administrator can cause a denial of service in WatchGuard Firebox management by sending crafted data to an unsafe deserialization endpoint.","url":"https://insights.sbomify.com/CVE-2026-13371/"}
