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-2025-57354 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- counterpart (npm): affected all versions up to 0.18.6; no fix listed\n- counterpart (npm): affected all versions up to 0.18.6; no fix listed\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-2025-57354/ (Markdown: https://insights.sbomify.com/CVE-2025-57354/index.md)","id":"CVE-2025-57354","markdown":"https://insights.sbomify.com/CVE-2025-57354/index.md","name":"CVE-2025-57354","record":{"aliases":["GHSA-2488-w585-72ch"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js translation library","requires_auth":"none","summary":"Prototype pollution in the counterpart library allows attackers to inject properties into the Object prototype, potentially leading to remote code execution or denial of service.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"A vulnerability exists in the 'counterpart' library for Node.js and the browser due to insufficient sanitization of user-controlled input in translation key processing. The affected versions prior to 0.18.6 allow attackers to manipulate the library's translation functionality by supplying maliciously crafted keys containing prototype chain elements (e.g., __proto__ ), leading to prototype pollution. This weakness enables adversaries to inject arbitrary properties into the JavaScript Object prototype through the first parameter of the translate method when combined with specific separator configurations, potentially resulting in denial-of-service conditions or remote code execution in vulnerable applications. The issue arises from the library's failure to properly validate or neutralize special characters in translation key inputs before processing.","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":false,"headline":"counterpart vulnerable to prototype pollution","id":"CVE-2025-57354","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2025"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-57389"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.18.6"],"package":"counterpart","purl":null,"source":"GHSA-2488-w585-72ch"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.18.6"],"package":"counterpart","purl":"pkg:npm/counterpart","source":"GHSA-2488-w585-72ch"}],"prev":{"headline":"messageformat prototype pollution vulnerability","id":"CVE-2025-57353"},"products":["n/a"],"published":"2025-09-24","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-09-25","vendors":["n/a"]},"summary":"Prototype pollution in the counterpart library allows attackers to inject properties into the Object prototype, potentially leading to remote code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2025-57354/"}
