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-2026-43943 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- electerm (npm): affected all versions; fixed in 3.7.9\n- electerm (npm): affected all versions; fixed in 3.7.9\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-2026-43943/ (Markdown: https://insights.sbomify.com/CVE-2026-43943/index.md)","id":"CVE-2026-43943","markdown":"https://insights.sbomify.com/CVE-2026-43943/index.md","name":"CVE-2026-43943","record":{"aliases":["GHSA-q4p8-8j9m-8hxj"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SSH client","requires_auth":"none","summary":"Attackers can execute arbitrary code on a victim's machine by crafting malicious filenames on a controlled SSH server when the user edits files.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"electerm","vendor":"electerm_project"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/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"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to version 3.7.9, a code execution (RCE) vulnerability exists in electerm's SFTP open with system editor or \"Edit with custom editor\" feature. When a user opts to edit a file using open with system editor or open with a custom editor, the filename is passed directly into a command line without sanitization. A malicious actor controlling the SSH server or user OS can exploit this by crafting a filename containing shell metacharacters. If a victim subsequently attempts to edit this file, the injected commands are executed on their machine with the user's privileges. This could allow the attacker to run arbitrary code, install malware, or move laterally within the network. This issue has been patched in version 3.7.9.","ecosystems":["npm"],"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":"electerm: RCE via malicious SSH server filename in openFileWithEditor","id":"CVE-2026-43943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"electerm: dangerous code can be run through links or command line","id":"CVE-2026-43944"},"packages":[{"ecosystem":"npm","fixed":["3.7.9"],"introduced":["0"],"last_affected":[],"package":"electerm","purl":null,"source":"GHSA-q4p8-8j9m-8hxj"},{"ecosystem":"npm","fixed":["3.7.9"],"introduced":["0"],"last_affected":[],"package":"electerm","purl":"pkg:npm/electerm","source":"GHSA-q4p8-8j9m-8hxj"}],"prev":{"headline":"electerm: Full process.env exposed to renderer via window.pre.env in electerm","id":"CVE-2026-43942"},"products":["electerm"],"published":"2026-05-08","related":[{"cvss_score":9.8,"headline":"electerm has Command Injection Vulnerability via runMac function","id":"CVE-2026-41500","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":9.8,"headline":"electerm has Command Injection Vulnerability via runLinux function","id":"CVE-2026-41501","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":9.8,"headline":"electerm allows unauthorized users to execute arbitrary commands","id":"CVE-2020-23256","kev_date_added":null,"published":"2023-01-20"},{"cvss_score":9.6,"headline":"Unvalidated shell.openExternal in electerm allows arbitrary protocol execution via terminal link click","id":"CVE-2026-43941","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":9.4,"headline":"electerm: dangerous code can be run through links or command line","id":"CVE-2026-43944","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":9.3,"headline":"electerm: Local code through electerm's single-instance socket","id":"CVE-2026-45353","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":8.4,"headline":"electerm: Path traversal in electerm runWidget leads to arbitrary code execution","id":"CVE-2026-43940","kev_date_added":null,"published":"2026-05-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-05-08","vendors":["electerm"]},"summary":"Attackers can execute arbitrary code on a victim's machine by crafting malicious filenames on a controlled SSH server when the user edits files.","url":"https://insights.sbomify.com/CVE-2026-43943/"}
