It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-5053 in the wild and no public exploit code.\n\nAffected product: NoMachine. 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-2026-5053/ (Markdown: https://insights.sbomify.com/CVE-2026-5053/index.md)","id":"CVE-2026-5053","markdown":"https://insights.sbomify.com/CVE-2026-5053/index.md","name":"CVE-2026-5053","record":{"aliases":["GHSA-75gg-gxqp-fq44"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NoMachine remote desktop","requires_auth":"low_privilege","summary":"Local attackers can delete arbitrary files as root due to improper path validation in NoMachine, requiring prior low-privileged code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"nomachine","vendor":"nomachine"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"NoMachine External Control of File Path Arbitrary File Deletion Vulnerability. This vulnerability allows local attackers to delete arbitrary files on affected installations of NoMachine.

The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to delete files in the context of root.
