It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-39199 exists.\n\nAffected product: Snes9X. 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-2026-39199/ (Markdown: https://insights.sbomify.com/CVE-2026-39199/index.md)","id":"CVE-2026-39199","markdown":"https://insights.sbomify.com/CVE-2026-39199/index.md","name":"CVE-2026-39199","record":{"aliases":["DEBIAN-CVE-2026-39199","GHSA-4qcp-g757-95hj","UBUNTU-CVE-2026-39199"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SNES emulator","requires_auth":"none","summary":"An attacker can cause an out-of-bounds write and denial of service in the Snes9x emulator by tricking a user into opening a crafted .ups file.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"snes9x 1.63 allows an out-of-bounds write and denial of service via a crafted .ups file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in Snes9X","id":"CVE-2026-39199","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"SQL injection in n/a","id":"CVE-2026-39229"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2026-39197"},"products":["Snes9X"],"published":"2026-06-17","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-17","vendors":["Snes9X team"]},"summary":"An attacker can cause an out-of-bounds write and denial of service in the Snes9x emulator by tricking a user into opening a crafted .ups file.","url":"https://insights.sbomify.com/CVE-2026-39199/"}
