Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-109354 in the wild and no public exploit code.\n\nAffected product: librenms. 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-2026-109354/ (Markdown: https://insights.sbomify.com/CVE-2026-109354/index.md)","id":"CVE-2026-109354","markdown":"https://insights.sbomify.com/CVE-2026-109354/index.md","name":"CVE-2026-109354","record":{"aliases":["GHSA-hr7h-8h3p-w7rx","GHSA-j3qf-h24w-9f42"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Network monitoring system","requires_auth":"low_privilege","summary":"Authenticated attackers can read unauthorized RRD data from other devices by exploiting a path traversal flaw in the NFSen channel parameter.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/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":"LibreNMS before 26.9.0 contains a path traversal vulnerability in nfsen_channel_common.inc.php that allows authenticated users to read unauthorized RRD data by injecting ../ sequences into the channel parameter.
