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-2020-37280 in the wild and no public exploit code.\n\nAffected product: PelionIoT cbor-sync. 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-2020-37280/ (Markdown: https://insights.sbomify.com/CVE-2020-37280/index.md)","id":"CVE-2020-37280","markdown":"https://insights.sbomify.com/CVE-2020-37280/index.md","name":"CVE-2020-37280","record":{"aliases":["GHSA-fpg7-639f-4v49"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CBOR parsing library","requires_auth":"none","summary":"Remote attackers can cause denial of service by sending crafted CBOR payloads that trigger excessive memory and CPU consumption in the cbor-sync library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"cbor-sync through 1.0.4 contains a resource exhaustion vulnerability in CBOR.decode that trusts declared array and map lengths without checking remaining input.
