It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-44467 in the wild and no public exploit code.\n\nAffected product: anthropics claude-code. 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-2026-44467/ (Markdown: https://insights.sbomify.com/CVE-2026-44467/index.md)","id":"CVE-2026-44467","markdown":"https://insights.sbomify.com/CVE-2026-44467/index.md","name":"CVE-2026-44467","record":{"aliases":[],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Claude Desktop app","requires_auth":"none","summary":"Attackers can intercept SSH traffic to perform man-in-the-middle attacks on remote development sessions due to missing host key verification.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"claude_desktop","vendor":"anthropic"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-322","name":"Key Exchange without Entity Authentication"},{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"The Claude Desktop app gives you Claude Code with a graphical interface built for running multiple sessions side by side. From 1.2581.0 to before 1.4304.0, Claude Desktop's SSH remote development feature verified only whether a hostname existed in ~/.ssh/known_hosts without comparing the server's presented host key against the stored key. This allowed a network-positioned attacker to present an arbitrary SSH host key and have the connection silently accepted, enabling a man-in-the-middle attack on remote development sessions. Successful exploitation required the attacker to be in a network position to intercept SSH traffic (e.g., via ARP spoofing, rogue Wi-Fi, or DNS poisoning) and the target hostname to already have an entry in the victim's known_hosts file. This vulnerability is fixed in 1.4304.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Claude Desktop: SSH Host Key Verification Bypass Allows Man-in-the-Middle Attack on Remote Sessions","id":"CVE-2026-44467","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Incorrect Default Permissions in CODESYS Development System","id":"CVE-2026-44468"},"packages":[],"prev":{"headline":"Zed: Allowlist Bypass via Bash Arithmetic Expansion in Terminal Tool Permissions","id":"CVE-2026-44466"},"products":["claude-code"],"published":"2026-05-13","related":[{"cvss_score":8.5,"headline":"Claude Desktop: Local Privilege Escalation via Directory Junction in CoworkVMService","id":"CVE-2026-44470","kev_date_added":null,"published":"2026-05-13"}],"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":"2026-05-14","vendors":["anthropics"]},"summary":"Attackers can intercept SSH traffic to perform man-in-the-middle attacks on remote development sessions due to missing host key verification.","url":"https://insights.sbomify.com/CVE-2026-44467/"}
