Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-71243 in the wild and no public exploit code.\n\nAffected product: adaltas backmeup. 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-2026-71243/ (Markdown: https://insights.sbomify.com/CVE-2026-71243/index.md)","id":"CVE-2026-71243","markdown":"https://insights.sbomify.com/CVE-2026-71243/index.md","name":"CVE-2026-71243","record":{"aliases":["GHSA-c6xg-rfqh-85cp"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js backup library","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands by injecting malicious characters into backup option values in the backmeup npm package.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"The backmeup npm package assembles shell command strings by directly concatenating its option values (name, source, destination, filter) - e.g. cmd = \"mkdir -p \" + path.join(info.destination, info.name) + \"; \" - and executes the resulting string through a shell via ssh2-exec (locally via child_process, or remotely via SSH when an ssh handle is supplied), rather than using execFile/spawn with an argument array.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"backmeup (npm) - OS Command Injection via Backup Option Values","id":"CVE-2026-71243","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Paperless-ngx - Mail Account Test Connection Leaks Stored IMAP/OAuth Credentials to Attacker-Controlled Host","id":"CVE-2026-71244"},"packages":[],"prev":{"headline":"Crater - Cross-Company IDOR on Notes via Missing Company-Ownership Check in NotePolicy","id":"CVE-2026-71242"},"products":["backmeup"],"published":"2026-08-05","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":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["adaltas"]},"summary":"Attackers can execute arbitrary OS commands by injecting malicious characters into backup option values in the backmeup npm package.","url":"https://insights.sbomify.com/CVE-2026-71243/"}
