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-2026-93862/ (Markdown: https://insights.sbomify.com/CVE-2026-93862/index.md)","id":"CVE-2026-93862","markdown":"https://insights.sbomify.com/CVE-2026-93862/index.md","name":"CVE-2026-93862","record":{"aliases":["GHSA-vq3j-9jcw-wpfh"],"analysis":null,"analysis_generated_by":null,"assigner":"WatchGuard","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-823","name":"Use of Out-of-range Pointer Offset"},{"id":"CWE-129","name":"Improper Validation of Array Index"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read vulnerability in the FireCluster Sync processing allows an attacker positioned on the cluster interconnect, such as a compromised cluster peer or an on-path network attacker, to repeatedly crash the firewall's cluster synchronization process by sending specially crafted network traffic, resulting in a sustained denial of service.","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 Out-of-Bounds Read in FireCluster Sync Allows Denial of Service","id":"CVE-2026-93862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Fireware OS Link Following in firewalld Allows Local Arbitrary File Overwrite as Root","id":"CVE-2026-93864"},"packages":[],"prev":{"headline":"Missing authorization in Mistral","id":"CVE-2026-93861"},"products":["Fireware OS"],"published":"2026-10-27","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["WatchGuard"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-93862/"}
