An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-27379 in the wild and no public exploit code.\n\nAffected product: Foxit Pdf Reader. 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-2023-27379/ (Markdown: https://insights.sbomify.com/CVE-2023-27379/index.md)","id":"CVE-2023-27379","markdown":"https://insights.sbomify.com/CVE-2023-27379/index.md","name":"CVE-2023-27379","record":{"aliases":["GHSA-3g2j-643p-qw2h"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"A use-after-free flaw in Foxit PDF Reader allows arbitrary code execution via malicious PDFs or websites, requiring user interaction.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"pdf_reader","vendor":"foxit"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/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 exists in the JavaScript engine of Foxit Software’s PDF Reader, version 12.1.2.15332.
