Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-39018 exists.\n\nAffected packages and fixed versions:\n- @cat5th/key-serializer (npm): affected all versions up to 0.2.5; no fix listed\n- @cat5th/key-serializer (npm): affected all versions up to 0.2.5; no fix listed\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-2024-39018/ (Markdown: https://insights.sbomify.com/CVE-2024-39018/index.md)","id":"CVE-2024-39018","markdown":"https://insights.sbomify.com/CVE-2024-39018/index.md","name":"CVE-2024-39018","record":{"aliases":["GHSA-whpx-g542-7c7v"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js serialization library","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code or cause denial of service via prototype pollution in the key-serializer library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"harvey-woo cat5th/key-serializer v0.2.5 was discovered to contain a prototype pollution via the function \"query\".
