Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-91006 in the wild and no public exploit code.\n\nAffected product: Apache Karaf. 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-2026-91006/ (Markdown: https://insights.sbomify.com/CVE-2026-91006/index.md)","id":"CVE-2026-91006","markdown":"https://insights.sbomify.com/CVE-2026-91006/index.md","name":"CVE-2026-91006","record":{"aliases":["GHSA-2wpj-35wr-vch7"],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java application server","requires_auth":"low_privilege","summary":"Attackers with access to instance management commands can execute arbitrary OS commands via unquoted javaOpts in Apache Karaf.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"karaf","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Apache Karaf's instance-management service (InstanceServiceImpl) builds the command line used to launch a child Karaf JVM by string concatenation, then executes it through /bin/sh (Unix) or cscript (Windows).
