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-2020-28503 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- copy-props (npm): affected all versions; fixed in 2.0.5\n- copy-props (npm): affected all versions; fixed in 2.0.5\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-2020-28503/ (Markdown: https://insights.sbomify.com/CVE-2020-28503/index.md)","id":"CVE-2020-28503","markdown":"https://insights.sbomify.com/CVE-2020-28503/index.md","name":"CVE-2020-28503","record":{"aliases":["GHSA-897m-rjf5-jp39"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"npm library","requires_auth":"none","summary":"Prototype pollution in copy-props allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"copy-props","vendor":"gulpjs"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O","version":"3.1"},"cwes":[],"description":"The package copy-props before 2.0.5 are vulnerable to Prototype Pollution via the main functionality.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Prototype Pollution","id":"CVE-2020-28503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"Privilege escalation in Trend Micro Apex One","id":"CVE-2020-28572"},"packages":[{"ecosystem":"npm","fixed":["2.0.5"],"introduced":["0"],"last_affected":[],"package":"copy-props","purl":null,"source":"GHSA-897m-rjf5-jp39"},{"ecosystem":"npm","fixed":["2.0.5"],"introduced":["0"],"last_affected":[],"package":"copy-props","purl":"pkg:npm/copy-props","source":"GHSA-897m-rjf5-jp39"}],"prev":{"headline":"Arbitrary Code Injection","id":"CVE-2020-28502"},"products":["copy-props"],"published":"2021-03-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Prototype pollution in copy-props allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2020-28503/"}
