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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-48711 exists.\n\nAffected product: libfuse sshfs. 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-2026-48711/ (Markdown: https://insights.sbomify.com/CVE-2026-48711/index.md)","id":"CVE-2026-48711","markdown":"https://insights.sbomify.com/CVE-2026-48711/index.md","name":"CVE-2026-48711","record":{"aliases":["ALPINE-CVE-2026-48711","AZL-97014","DEBIAN-CVE-2026-48711","GHSA-mm85-q63v-4476","UBUNTU-CVE-2026-48711"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"SSHFS network filesystem","requires_auth":"none","summary":"Attackers can execute arbitrary commands locally by injecting options into SSHFS mount sources when specific sftp_server configurations are used.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"SSHFS is a network filesystem client for connecting to SSH servers. From version 1.4 until 3.7.6, SSHFS accepts a bracketed mount source such as [-oProxyCommand=CMD]:/path and find_base_path() removes the brackets, leaving a host value that begins with - and is passed directly to ssh as a command-line argument. When a caller also supplies a path-valued sftp_server, ssh treats the normalized host as an option and the server path as its destination, causing an injected ProxyCommand to execute locally before any connection or authentication succeeds. The attack requires a caller or wrapper that passes an attacker-controlled mount source to SSHFS with the required sftp_server configuration and results in arbitrary command execution as the user running SSHFS. This issue is fixed in version 3.7.6.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"SSHFS: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')","id":"CVE-2026-48711","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"protobufjs: Denial of service through unbounded Any expansion during JSON conversion","id":"CVE-2026-48712"},"packages":[],"prev":{"headline":"Kludex Starlette HTTP Request/Response Smuggling","id":"CVE-2026-48710"},"products":["sshfs"],"published":"2026-08-19","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-20","vendors":["libfuse"]},"summary":"Attackers can execute arbitrary commands locally by injecting options into SSHFS mount sources when specific sftp_server configurations are used.","url":"https://insights.sbomify.com/CVE-2026-48711/"}
