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-2026-103390/ (Markdown: https://insights.sbomify.com/CVE-2026-103390/index.md)","id":"CVE-2026-103390","markdown":"https://insights.sbomify.com/CVE-2026-103390/index.md","name":"CVE-2026-103390","record":{"aliases":["GHSA-3f2f-h3c9-56gv"],"analysis":null,"analysis_generated_by":null,"assigner":"juniper","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An Out-of-Bounds Read vulnerability in the HttpParser component in Juniper Networks Session Smart Router and Session Smart Conductor allows an attacker to cause a denial of service via a specially crafted HTTP 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":"An Out-of-Bounds Read vulnerability in the HttpParser component in Juniper Networks Session Smart Router and Session Smart Conductor allows","id":"CVE-2026-103390","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Session Smart Router: An attacker-controlled TCP option causes an out-of-bounds write when using the TCP proxy feature","id":"CVE-2026-103391"},"packages":[],"prev":{"headline":"MISP Stored Cross-Site Scripting via Unvalidated Galaxy Icon Field in Correlation Graph","id":"CVE-2026-103389"},"products":["Session Smart Conductor","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Juniper Networks"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-103390/"}
