It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-3738 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- protobufjs (npm): affected all versions; fixed in 5.0.3\n- protobufjs (npm): affected all versions; fixed in 5.0.3\n- protobufjs (npm): affected from 6.0.0; fixed in 6.8.6\n- protobufjs (npm): affected from 6.0.0; fixed in 6.8.6\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-2018-3738/ (Markdown: https://insights.sbomify.com/CVE-2018-3738/index.md)","id":"CVE-2018-3738","markdown":"https://insights.sbomify.com/CVE-2018-3738/index.md","name":"CVE-2018-3738","record":{"aliases":["CLSA-2026-1785291242","GHSA-762f-c2wg-m8c8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JavaScript protobuf library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using protobufjs by supplying crafted invalid .proto files that trigger excessive CPU consumption.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"protobufjs","vendor":"protobufjs_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-185","name":"Incorrect Regular Expression"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"protobufjs is vulnerable to ReDoS when parsing crafted invalid .proto files.","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":"Denial of Service in protobufjs","id":"CVE-2018-3738","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":4,"n_references":1,"next":{"headline":"Denial of Service in https-proxy-agent","id":"CVE-2018-3739"},"packages":[{"ecosystem":"npm","fixed":["5.0.3"],"introduced":["0"],"last_affected":[],"package":"protobufjs","purl":null,"source":"GHSA-762f-c2wg-m8c8"},{"ecosystem":"npm","fixed":["5.0.3"],"introduced":["0"],"last_affected":[],"package":"protobufjs","purl":"pkg:npm/protobufjs","source":"GHSA-762f-c2wg-m8c8"},{"ecosystem":"npm","fixed":["6.8.6"],"introduced":["6.0.0"],"last_affected":[],"package":"protobufjs","purl":null,"source":"GHSA-762f-c2wg-m8c8"},{"ecosystem":"npm","fixed":["6.8.6"],"introduced":["6.0.0"],"last_affected":[],"package":"protobufjs","purl":"pkg:npm/protobufjs","source":"GHSA-762f-c2wg-m8c8"}],"prev":{"headline":"Regular Expression Denial of Service in sshpk","id":"CVE-2018-3737"},"products":["protobufjs node module"],"published":"2018-06-07","related":[{"cvss_score":9.8,"headline":"protobufjs Prototype Pollution vulnerability","id":"CVE-2023-36665","kev_date_added":null,"published":"2023-07-05"},{"cvss_score":9.4,"headline":"protobufjs has an arbitrary code execution issue","id":"CVE-2026-41242","kev_date_added":null,"published":"2026-04-18"},{"cvss_score":8.2,"headline":"Prototype Pollution","id":"CVE-2022-25878","kev_date_added":null,"published":"2022-05-27"},{"cvss_score":8.1,"headline":"protobufjs: Code generation gadget after prototype pollution","id":"CVE-2026-44291","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":7.7,"headline":"protobufjs: Code injection through bytes field defaults in generated toObject code","id":"CVE-2026-44293","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":7.5,"headline":"protobufjs: Denial of service through unbounded Any expansion during JSON conversion","id":"CVE-2026-48712","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":7.5,"headline":"protobufjs: Denial of service through unbounded protobuf recursion","id":"CVE-2026-44289","kev_date_added":null,"published":"2026-05-13"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["HackerOne"]},"summary":"Attackers can cause denial of service in applications using protobufjs by supplying crafted invalid .proto files that trigger excessive CPU consumption.","url":"https://insights.sbomify.com/CVE-2018-3738/"}
