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-2020-26245 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- systeminformation (npm): affected all versions; fixed in 4.30.5\n- systeminformation (npm): affected all versions; fixed in 4.30.5\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-2020-26245/ (Markdown: https://insights.sbomify.com/CVE-2020-26245/index.md)","id":"CVE-2020-26245","markdown":"https://insights.sbomify.com/CVE-2020-26245/index.md","name":"CVE-2020-26245","record":{"aliases":["GHSA-4v2w-h9jm-mqjg"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js system info library","requires_auth":"none","summary":"Attackers can execute arbitrary commands via prototype pollution in the systeminformation npm package when processing service parameters.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"systeminformation","vendor":"systeminformation"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-471","name":"Modification of Assumed-Immutable Data (MAID)"}],"description":"npm package systeminformation before version 4.30.5 is vulnerable to Prototype Pollution leading to Command Injection.
