It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-73974 exists.\n\nAffected packages and fixed versions:\n- linuxfabrik-lib (PyPI): affected all versions; fixed in 6.1.0\n- linuxfabrik-lib (PyPI): affected all versions; fixed in 6.1.0\n- linuxfabrik-lib (PyPI): affected all versions; fixed in 6.1.0\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-2026-73974/ (Markdown: https://insights.sbomify.com/CVE-2026-73974/index.md)","id":"CVE-2026-73974","markdown":"https://insights.sbomify.com/CVE-2026-73974/index.md","name":"CVE-2026-73974","record":{"aliases":["GHSA-rh9c-rqvg-f7pr","PYSEC-2026-3682"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linuxfabrik monitoring plugins","requires_auth":"low_privilege","summary":"Attackers with monitoring account access can read arbitrary root files via a hidden test argument in Linuxfabrik plugins, leading to information disclosure and privilege escalation.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations, and Linuxfabrik Monitoring Plugins uses its shared testing helper across check plugins. Prior to linuxfabrik-lib 6.1.0 and Linuxfabrik Monitoring Plugins 7.0.0, lib.lftest.test() treated the first or second element of a --test CSV argument as a filesystem path and returned the file contents as simulated standard output or standard error without path confinement. The hidden but production-accessible --test argument was accepted by sudo-authorized plugins, so an attacker controlling the nagios or icinga account could use check-plugins/deb-updates/deb-updates with its default QUERY=1 to disclose every line of a root-readable file. Approximately 22 other plugins exposed filtered content or a root file existence and readability oracle through the same helper, while check-plugins/network-bonding/network-bonding and check-plugins/openstack-swift-stat/openstack-swift-stat had direct read paths that bypassed the helper. The library fix confines fixture reads to the invoking plugin's unit-test directory and refuses unsafe anchors, and the plugin fix routes the two bypasses through that helper. These issues are fixed in linuxfabrik-lib 6.1.0 and Linuxfabrik Monitoring Plugins 7.0.0.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"linuxfabrik-lib: Arbitrary root file read via live --test argument (lib.lftest) across sudoers-whitelisted plugins (LPE)","id":"CVE-2026-73974","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":3,"n_references":5,"next":{"headline":"djehuty: Authenticated SPARQL injection in session editing allows writing arbitrary RDF triples","id":"CVE-2026-73975"},"packages":[{"ecosystem":"PyPI","fixed":["6.1.0"],"introduced":["0"],"last_affected":[],"package":"linuxfabrik-lib","purl":null,"source":"GHSA-rh9c-rqvg-f7pr"},{"ecosystem":"PyPI","fixed":["6.1.0"],"introduced":["0"],"last_affected":[],"package":"linuxfabrik-lib","purl":"pkg:pypi/linuxfabrik-lib","source":"GHSA-rh9c-rqvg-f7pr"},{"ecosystem":"PyPI","fixed":["6.1.0"],"introduced":["0"],"last_affected":[],"package":"linuxfabrik-lib","purl":"pkg:pypi/linuxfabrik-lib","source":"PYSEC-2026-3682"}],"prev":{"headline":"Path traversal in monitoring-plugins","id":"CVE-2026-73973"},"products":["lib","monitoring-plugins"],"published":"2026-08-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Linuxfabrik"]},"summary":"Attackers with monitoring account access can read arbitrary root files via a hidden test argument in Linuxfabrik plugins, leading to information disclosure and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-73974/"}
