Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100520 in the wild and no public exploit code.\n\nAffected product: crivion Laranode. 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-2026-100520/ (Markdown: https://insights.sbomify.com/CVE-2026-100520/index.md)","id":"CVE-2026-100520","markdown":"https://insights.sbomify.com/CVE-2026-100520/index.md","name":"CVE-2026-100520","record":{"aliases":["GHSA-34h2-2696-vfvr","GHSA-7q7h-5g76-8cq4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Laranode web application","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit path traversal in the file upload endpoint to write arbitrary files and execute code as other tenants.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Laranode versions before 1.2.1 contain a path traversal vulnerability in the POST /filemanager/upload-file endpoint that allows authenticated users to write arbitrary files outside their home directory.
