Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-25228 exists.\n\nAffected packages and fixed versions:\n- signalk-server (npm): affected all versions; fixed in 2.20.3\n- signalk-server (npm): affected all versions; fixed in 2.20.3\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-2026-25228/ (Markdown: https://insights.sbomify.com/CVE-2026-25228/index.md)","id":"CVE-2026-25228","markdown":"https://insights.sbomify.com/CVE-2026-25228/index.md","name":"CVE-2026-25228","record":{"aliases":["GHSA-vrhw-v2hw-jffx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SignalK Server","requires_auth":"low_privilege","summary":"Authenticated attackers on Windows can read, write, and list arbitrary files via path traversal in the applicationData API.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"signal_k_server","vendor":"signalk"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Signal K Server is a server application that runs on a central hub in a boat. Prior to 2.20.3, a path traversal vulnerability in SignalK Server's applicationData API allows authenticated users on Windows systems to read, write, and list arbitrary files and directories on the filesystem. The validateAppId() function blocks forward slashes (/) but not backslashes (\\), which are treated as directory separators by path.join() on Windows. This enables attackers to escape the intended applicationData directory.
