An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4591 in the wild and no public exploit code.\n\nAffected product: kalcaddle kodbox. 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-2026-4591/ (Markdown: https://insights.sbomify.com/CVE-2026-4591/index.md)","id":"CVE-2026-4591","markdown":"https://insights.sbomify.com/CVE-2026-4591/index.md","name":"CVE-2026-4591","record":{"aliases":["GHSA-rjfv-p85j-26xf"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"kodbox file manager","requires_auth":"high_privilege","summary":"Remote attackers can execute arbitrary OS commands via the fileThumb endpoint in kodbox, leading to potential system compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A weakness has been identified in kalcaddle kodbox 1.64.
