An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-25914 exists.\n\nAffected packages and fixed versions:\n- object-collider (npm): affected from 1.0.0; fixed in 1.0.4\n- object-collider (npm): affected from 1.0.0; fixed in 1.0.4\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-2021-25914/ (Markdown: https://insights.sbomify.com/CVE-2021-25914/index.md)","id":"CVE-2021-25914","markdown":"https://insights.sbomify.com/CVE-2021-25914/index.md","name":"CVE-2021-25914","record":{"aliases":["GHSA-85g2-29m8-qf2p"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"npm object-collider library","requires_auth":"none","summary":"Prototype pollution in object-collider allows attackers to cause denial of service and potentially execute remote code.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mend","cpe":[{"product":"object-collider","vendor":"fireblink"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Prototype pollution vulnerability in 'object-collider' versions 1.0.0 through 1.0.3 allows attacker to cause a denial of service and may lead to remote code execution.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Prototype Pollution Vulnerability in object-collider","id":"CVE-2021-25914","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Changeset vulnerable to prototype pollution","id":"CVE-2021-25915"},"packages":[{"ecosystem":"npm","fixed":["1.0.4"],"introduced":["1.0.0"],"last_affected":[],"package":"object-collider","purl":null,"source":"GHSA-85g2-29m8-qf2p"},{"ecosystem":"npm","fixed":["1.0.4"],"introduced":["1.0.0"],"last_affected":[],"package":"object-collider","purl":"pkg:npm/object-collider","source":"GHSA-85g2-29m8-qf2p"}],"prev":{"headline":"Prototype Pollution in set-or-get","id":"CVE-2021-25913"},"products":["object-collider"],"published":"2021-03-01","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-30","vendors":["n/a"]},"summary":"Prototype pollution in object-collider allows attackers to cause denial of service and potentially execute remote code.","url":"https://insights.sbomify.com/CVE-2021-25914/"}
