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-2017-11909 exists.\n\nAffected packages and fixed versions:\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.7.5\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.7.5\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-2017-11909/ (Markdown: https://insights.sbomify.com/CVE-2017-11909/index.md)","id":"CVE-2017-11909","markdown":"https://insights.sbomify.com/CVE-2017-11909/index.md","name":"CVE-2017-11909","record":{"aliases":["GHSA-9qpf-v72j-j9qh"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge","requires_auth":"none","summary":"An attacker can execute arbitrary code in the context of the current user via a memory corruption flaw in the ChakraCore scripting engine used by Microsoft 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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"ChakraCore and Windows 10 1511, 1607, 1703, 1709, and Windows Server 2016 allows an attacker to execute arbitrary code in the context of the current user, due to how the scripting engine handles objects in memory, aka \"Scripting Engine Memory Corruption Vulnerability\".
