An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-82853 exists.\n\nAffected packages and fixed versions:\n- nodemailer (npm): affected all versions; fixed in 8.0.5\n- nodemailer (npm): affected all versions; fixed in 8.0.5\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-2026-82853/ (Markdown: https://insights.sbomify.com/CVE-2026-82853/index.md)","id":"CVE-2026-82853","markdown":"https://insights.sbomify.com/CVE-2026-82853/index.md","name":"CVE-2026-82853","record":{"aliases":["CLEANSTART-2026-XN13622","DEBIAN-CVE-2026-82853","ECHO-2e01-a0c3-6c54","GHSA-q8rv-95x3-46j5","GHSA-vvjj-xcjg-gr5g","MINI-22wh-3chv-vj75","MINI-325r-qxxm-27w8","MINI-5568-hxhp-2h8j","MINI-6jgf-h5fv-6vp3","MINI-6xqv-p284-w7v2","MINI-8wh7-r2qj-q8pv","MINI-crwx-w6vw-vg7p","MINI-fmw8-977x-pm7h","MINI-fx9g-qpv3-4grh","MINI-g4r8-wvmq-6g9h","MINI-mg75-9mhv-c843","MINI-q7p4-r7cx-g883","MINI-r6cf-rjv5-r7px","MINI-vm7h-4hq9-pw2m","MINI-wq4q-92h7-3mjg","MINI-x4f9-rqrc-2wxg","MINI-x4rm-2j75-vw92","ROOT-APP-NPM-GHSA-vvjj-xcjg-gr5g","UBUNTU-CVE-2026-82853"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js email library","requires_auth":"high_privilege","summary":"Attackers can inject arbitrary SMTP commands via the transport name option, enabling email spoofing and phishing attacks.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"Nodemailer versions before 8.0.5 contain an SMTP command injection vulnerability in the transport name option used in EHLO/HELO commands.
