An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-66050 exists.\n\nAffected product: nitroshare-desktop. 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-2026-66050/ (Markdown: https://insights.sbomify.com/CVE-2026-66050/index.md)","id":"CVE-2026-66050","markdown":"https://insights.sbomify.com/CVE-2026-66050/index.md","name":"CVE-2026-66050","record":{"aliases":["GHSA-5xhx-w5wq-c68v"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"NitroShare Desktop","requires_auth":"none","summary":"Unauthenticated attackers on the local network can write arbitrary files via path traversal, potentially achieving persistent code execution on the victim's machine.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"NitroShare Desktop through 0.3.4 contains a path traversal vulnerability in its LAN file transfer server that allows unauthenticated attackers on the same network to write arbitrary files by sending a crafted filename containing directory traversal sequences in the JSON item header name field.
