An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-43863 in the wild and no public exploit code.\n\nAffected product: mutt. 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-2026-43863/ (Markdown: https://insights.sbomify.com/CVE-2026-43863/index.md)","id":"CVE-2026-43863","markdown":"https://insights.sbomify.com/CVE-2026-43863/index.md","name":"CVE-2026-43863","record":{"aliases":["AZL-85590","DEBIAN-CVE-2026-43863","GHSA-g7m5-w98f-vqg2","UBUNTU-CVE-2026-43863"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Email client","requires_auth":"none","summary":"An attacker can cause a denial of service in the Mutt email client by triggering an infinite loop during GPG cryptographic operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-253","name":"Incorrect Check of Function Return Value"}],"description":"mutt before 2.3.2 has an infinite loop in data_object_to_stream in crypt-gpgme.c.","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 mutt","id":"CVE-2026-43863","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in mutt","id":"CVE-2026-43864"},"packages":[],"prev":{"headline":"Security feature bypass in mutt","id":"CVE-2026-43862"},"products":["mutt"],"published":"2026-05-04","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":"2026-05-04","vendors":["mutt"]},"summary":"An attacker can cause a denial of service in the Mutt email client by triggering an infinite loop during GPG cryptographic operations.","url":"https://insights.sbomify.com/CVE-2026-43863/"}
