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-2026-13006 in the wild and no public exploit code.\n\nAffected product: QOS.CH Sarl Logback-core. 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-2026-13006/ (Markdown: https://insights.sbomify.com/CVE-2026-13006/index.md)","id":"CVE-2026-13006","markdown":"https://insights.sbomify.com/CVE-2026-13006/index.md","name":"CVE-2026-13006","record":{"aliases":["CLEANSTART-2026-GB27003","CLEANSTART-2026-SP20154","CLEANSTART-2026-XN09213","DEBIAN-CVE-2026-13006","GHSA-567r-vvh5-jjr8","UBUNTU-CVE-2026-13006","openSUSE-SU-2026:11135-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Java logging library","requires_auth":"high_privilege","summary":"Attackers with existing privileges can execute arbitrary code in Java applications using Logback-core by manipulating configuration files or environment variables.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N/S:P/AU:N/RE:M/U:Green","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"ACE vulnerability in conditional configuration file processing  by QOS.CH logback-core up to and including version 1.5.36 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution.\n\nA successful attack requires the presence of Janino library to be present on the user's class path.
