An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-1000216 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-1000216/ (Markdown: https://insights.sbomify.com/CVE-2018-1000216/index.md)","id":"CVE-2018-1000216","markdown":"https://insights.sbomify.com/CVE-2018-1000216/index.md","name":"CVE-2018-1000216","record":{"aliases":["AZL-41848","GHSA-3g82-r8f2-r5vq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"cJSON library","requires_auth":"none","summary":"A double free vulnerability in the cJSON library allows attackers to cause crashes or execute arbitrary code by forcing the victim to print JSON data.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cjson","vendor":"davegamble"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"Dave Gamble cJSON version 1.7.2 and earlier contains a CWE-415: Double Free vulnerability in cJSON library that can result in Possible crash or RCE.
