An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-6204 exists.\n\nAffected packages and fixed versions:\n- librenms/librenms (Packagist): affected from 1.48; fixed in 26.3.0\n- librenms/librenms (Packagist): affected from 1.48; fixed in 26.3.0\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-2026-6204/ (Markdown: https://insights.sbomify.com/CVE-2026-6204/index.md)","id":"CVE-2026-6204","markdown":"https://insights.sbomify.com/CVE-2026-6204/index.md","name":"CVE-2026-6204","record":{"aliases":["GHSA-pr3g-phhr-h8fh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Network monitoring system","requires_auth":"high_privilege","summary":"Authenticated administrators can achieve remote code execution on the web server by abusing Binary Locations config and Netcommand features.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PRJBLK","cpe":[{"product":"librenms","vendor":"librenms"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"LibreNMS versions before 26.3.0 are affected by an authenticated remote code execution vulnerability by abusing the Binary Locations config and the Netcommand feature.
