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-2026-38728 exists.\n\nAffected packages and fixed versions:\n- smtp-server (npm): affected all versions; fixed in 3.18.3\n- smtp-server (npm): affected all versions; fixed in 3.18.3\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-2026-38728/ (Markdown: https://insights.sbomify.com/CVE-2026-38728/index.md)","id":"CVE-2026-38728","markdown":"https://insights.sbomify.com/CVE-2026-38728/index.md","name":"CVE-2026-38728","record":{"aliases":["GHSA-fv2f-rw9f-v9cm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js SMTP library","requires_auth":"none","summary":"A remote attacker can cause a denial of service in Nodemailer smtp_server via the SMTPStream._write component.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"An issue in Nodemailer smtp_server before v.3.18.3 allows a remote attacker to cause a denial of service via the SMTPStream._write, lib/smtp-stream.js components","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":"smtp-server's command parser memory exhaustion denial-of-service","id":"CVE-2026-38728","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2026-38740"},"packages":[{"ecosystem":"npm","fixed":["3.18.3"],"introduced":["0"],"last_affected":[],"package":"smtp-server","purl":null,"source":"GHSA-fv2f-rw9f-v9cm"},{"ecosystem":"npm","fixed":["3.18.3"],"introduced":["0"],"last_affected":[],"package":"smtp-server","purl":"pkg:npm/smtp-server","source":"GHSA-fv2f-rw9f-v9cm"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2026-38725"},"products":["n/a"],"published":"2026-05-15","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["n/a"]},"summary":"A remote attacker can cause a denial of service in Nodemailer smtp_server via the SMTPStream._write component.","url":"https://insights.sbomify.com/CVE-2026-38728/"}
