An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-45311 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- fsevents (npm): affected all versions; fixed in 1.2.11\n- fsevents (npm): affected all versions; fixed in 1.2.11\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-2023-45311/ (Markdown: https://insights.sbomify.com/CVE-2023-45311/index.md)","id":"CVE-2023-45311","markdown":"https://insights.sbomify.com/CVE-2023-45311/index.md","name":"CVE-2023-45311","record":{"aliases":["GHSA-8r6j-v8pm-fqw3","UBUNTU-CVE-2023-45311"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js file events library","requires_auth":"none","summary":"An adversary could execute arbitrary code by controlling the external binary download URL used by the fsevents library.","user_interaction":"not_required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fsevents","vendor":"fsevents_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"fsevents before 1.2.11 depends on the https://fsevents-binaries.s3-us-west-2.amazonaws.com URL, which might allow an adversary to execute arbitrary code if any JavaScript project (that depends on fsevents) distributes code that was obtained from that URL at a time when it was controlled by an adversary.
