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-2018-0934 exists.\n\nAffected packages and fixed versions:\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.8.2\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.8.2\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-2018-0934/ (Markdown: https://insights.sbomify.com/CVE-2018-0934/index.md)","id":"CVE-2018-0934","markdown":"https://insights.sbomify.com/CVE-2018-0934/index.md","name":"CVE-2018-0934","record":{"aliases":["GHSA-phcc-frh9-q545"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Chakra Engine","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by exploiting a memory corruption flaw in the Chakra scripting engine within Windows and Edge.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"chakracore","vendor":"microsoft"},{"product":"edge","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-787","name":"Out-of-bounds Write"},{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"}],"description":"ChakraCore and Microsoft Windows 10 Gold, 1511, 1607, 1703, 1709, and Windows Server 2016 allows remote code execution, due to how the Chakra scripting engine handles objects in memory, aka \"Chakra Scripting Engine Memory Corruption Vulnerability\".
