An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-62642 in the wild and no public exploit code.\n\nAffected product: Roundcube Webmail. 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-2026-62642/ (Markdown: https://insights.sbomify.com/CVE-2026-62642/index.md)","id":"CVE-2026-62642","markdown":"https://insights.sbomify.com/CVE-2026-62642/index.md","name":"CVE-2026-62642","record":{"aliases":["DEBIAN-CVE-2026-62642","GHSA-345h-r9m2-jr4p","UBUNTU-CVE-2026-62642"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Roundcube Webmail","requires_auth":"none","summary":"An attacker can cause a denial of service by sending an email with a malicious TNEF attachment, affecting Roundcube Webmail users.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"webmail","vendor":"roundcube"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"In Roundcube Webmail before 1.6.17 and 1.7.x before 1.7.2, an infinite loop was discovered in the TNEF decoder, which may lead to denial of service upon opening an email with a TNEF attachment.","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":"Denial of service in Webmail","id":"CVE-2026-62642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"roundcube:webmail","products":["roundcube:webmail"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"Server-side request forgery in Webmail","id":"CVE-2026-62643"},"packages":[],"prev":{"headline":"Denial of service in Webmail","id":"CVE-2026-62641"},"products":["Webmail"],"published":"2026-07-14","related":[{"cvss_score":9.3,"headline":"RoundCube Webmail Cross-Site Scripting","id":"CVE-2024-42009","kev_date_added":"2025-06-09","published":"2024-08-05"},{"cvss_score":7.2,"headline":"RoundCube Webmail Cross-site Scripting","id":"CVE-2025-68461","kev_date_added":"2026-02-20","published":"2025-12-18"},{"cvss_score":10,"headline":"PHPMailer susceptible to arbitrary code execution","id":"CVE-2008-5619","kev_date_added":null,"published":"2008-12-17"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2024-37385","kev_date_added":null,"published":"2024-06-07"},{"cvss_score":9.3,"headline":"Cross-site scripting in n/a","id":"CVE-2024-42008","kev_date_added":null,"published":"2024-08-05"},{"cvss_score":8.8,"headline":"Command injection in Webmail","id":"CVE-2026-74997","kev_date_added":null,"published":"2026-08-17"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-8114","kev_date_added":null,"published":"2017-04-29"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["Roundcube"]},"summary":"An attacker can cause a denial of service by sending an email with a malicious TNEF attachment, affecting Roundcube Webmail users.","url":"https://insights.sbomify.com/CVE-2026-62642/"}
