Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-40204 in the wild and no public exploit code.\n\nAffected product: Open-Xchange GmbH OX Dovecot CE. 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-2026-40204/ (Markdown: https://insights.sbomify.com/CVE-2026-40204/index.md)","id":"CVE-2026-40204","markdown":"https://insights.sbomify.com/CVE-2026-40204/index.md","name":"CVE-2026-40204","record":{"aliases":["AZL-98301","DEBIAN-CVE-2026-40204","GHSA-wxgx-37c3-39ph","UBUNTU-CVE-2026-40204"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Dovecot mail server","requires_auth":"low_privilege","summary":"An authentication bypass vulnerability in Open-Xchange Dovecot allows attackers to circumvent security controls.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"None None None No publicly available exploits are known.","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":"Auth bypass in OX Dovecot CE","id":"CVE-2026-40204","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in OX Dovecot CE","id":"CVE-2026-40205"},"packages":[],"prev":{"headline":"Information disclosure in OX Dovecot CE","id":"CVE-2026-40203"},"products":["OX Dovecot CE","OX Dovecot Pro"],"published":"2026-08-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-28","vendors":["Open-Xchange GmbH"]},"summary":"An authentication bypass vulnerability in Open-Xchange Dovecot allows attackers to circumvent security controls.","url":"https://insights.sbomify.com/CVE-2026-40204/"}
