It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2018-4878 in the wild since at least 3 Nov 2021, including in ransomware campaigns.\n\nAffected product: Adobe Flash Player. 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-2018-4878/ (Markdown: https://insights.sbomify.com/CVE-2018-4878/index.md)","id":"CVE-2018-4878","markdown":"https://insights.sbomify.com/CVE-2018-4878/index.md","name":"CVE-2018-4878","record":{"aliases":["GHSA-2rf4-mpg3-phjw","UBUNTU-CVE-2018-4878"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe Flash Player","requires_auth":"none","summary":"A use-after-free flaw in Adobe Flash Player allows attackers to execute arbitrary code via malicious media content, requiring an upgrade to the latest version.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"flash_player","vendor":"adobe"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161.
