It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-66140 in the wild and no public exploit code.\n\nAffected product: Exim Exim. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-66140/ (Markdown: https://insights.sbomify.com/CVE-2026-66140/index.md)","id":"CVE-2026-66140","markdown":"https://insights.sbomify.com/CVE-2026-66140/index.md","name":"CVE-2026-66140","record":{"aliases":["DEBIAN-CVE-2026-66140","GHSA-5qxf-w5v2-m3rg","ROOT-OS-DEBIAN-11-CVE-2026-66140","ROOT-OS-DEBIAN-12-CVE-2026-66140","UBUNTU-CVE-2026-66140"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Exim mail server","requires_auth":"none","summary":"Attackers can traverse directories to access files outside the spool area and gain privileges due to mishandled queue-name arguments in Exim.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exim","vendor":"exim"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-24","name":"Path Traversal: '../filedir'"}],"description":"Exim before 4.99.5 allows directory traversal to access files outside of the spool area, and consequently gain privileges, because arguments related to queue-name are mishandled.","ecosystems":[],"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":"Path traversal in Exim","id":"CVE-2026-66140","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exim:exim","products":["exim:exim"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Exim","id":"CVE-2026-66141"},"packages":[],"prev":{"headline":"Auth bypass in Zaqar","id":"CVE-2026-66139"},"products":["Exim"],"published":"2026-07-24","related":[{"cvss_score":9.8,"headline":"Use after free in Exim","id":"CVE-2026-45185","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.8,"headline":"Exim AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2023-42115","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28017","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-28018","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28020","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28022","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28024","kev_date_added":null,"published":"2021-05-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-24","vendors":["Exim"]},"summary":"Attackers can traverse directories to access files outside the spool area and gain privileges due to mishandled queue-name arguments in Exim.","url":"https://insights.sbomify.com/CVE-2026-66140/"}
