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-2026-114198/ (Markdown: https://insights.sbomify.com/CVE-2026-114198/index.md)","id":"CVE-2026-114198","markdown":"https://insights.sbomify.com/CVE-2026-114198/index.md","name":"CVE-2026-114198","record":{"aliases":["GHSA-99jr-jxwf-6chm"],"analysis":null,"analysis_generated_by":null,"assigner":"Mandiant","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of untrusted data in Mandiant FLARE floss releases before 3.2.0 allows arbitrary code execution when a crafted .viv or .exe.viv workspace is passed to the floss utility","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":"Deserialization of untrusted data in floss","id":"CVE-2026-114198","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WebSocket 1-byte continuation frames bypass `max_fragmented_message_size` in Bandit","id":"CVE-2026-114213"},"packages":[],"prev":{"headline":"Deserialization of untrusted data in capa","id":"CVE-2026-114197"},"products":["floss"],"published":"2026-10-21","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":"total"},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Mandiant FLARE"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-114198/"}
