An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-8353 exists.\n\nAffected product: Microsoft Internet Explorer. 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-2018-8353/ (Markdown: https://insights.sbomify.com/CVE-2018-8353/index.md)","id":"CVE-2018-8353","markdown":"https://insights.sbomify.com/CVE-2018-8353/index.md","name":"CVE-2018-8353","record":{"aliases":["GHSA-r7hq-ppp5-wmmx"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a use-after-free vulnerability in the Internet Explorer scripting engine.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"internet_explorer","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer, aka \"Scripting Engine Memory Corruption Vulnerability.\" This affects Internet Explorer 9, Internet Explorer 11, Internet Explorer 10.
