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-2026-103408/ (Markdown: https://insights.sbomify.com/CVE-2026-103408/index.md)","id":"CVE-2026-103408","markdown":"https://insights.sbomify.com/CVE-2026-103408/index.md","name":"CVE-2026-103408","record":{"aliases":["GHSA-mg6q-7pjx-486r"],"analysis":null,"analysis_generated_by":null,"assigner":"juniper","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A Stack Buffer Overflow vulnerability in the DHCP client in Juniper Networks Session Smart Router allows an unauthenticated attacker on the local network to achieve remote code execution via a malicious DHCP reply.","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":"Session Smart Router: An attacker-controlled input causes remote code execution when parsing DHCP options","id":"CVE-2026-103408","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"A Missing authentication for critical function vulnerability in Juniper Networks Session Smart Router allows an unauthenticated network-base","id":"CVE-2026-103409"},"packages":[],"prev":{"headline":"An Improper Limitation of a Pathname to a Restricted Directory vulnerability in ConfigDirector in Juniper Networks Session Smart Router and","id":"CVE-2026-103407"},"products":["Session Smart Router"],"published":"2026-10-28","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Juniper Networks"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-103408/"}
