An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44257 exists.\n\nAffected product: efwGrp efw4.X. 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-2026-44257/ (Markdown: https://insights.sbomify.com/CVE-2026-44257/index.md)","id":"CVE-2026-44257","markdown":"https://insights.sbomify.com/CVE-2026-44257/index.md","name":"CVE-2026-44257","record":{"aliases":["GHSA-q7jx-7x5r-r9f6"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Enterprise Web Framework","requires_auth":"none","summary":"Remote attackers can upload malicious ZIP files to execute arbitrary code via path traversal in the file manager.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"efw4.X is an Enterprise Framework for Web. Prior to 4.08.010, efw.file.FileManager.unZip writes zip entries to disk using new File(baseDir, zipEntry.getName()) with no canonical-path check. An entry name such as ../../../pwned.jsp escapes the intended extraction directory and lands anywhere the Tomcat process can write — including the servlet context root. Combined with the framework's multipart /uploadServlet and an event that calls file.saveUploadFiles + FileManager.unZip, a remote attacker with no credentials drops a JSP webshell and executes arbitrary commands as the Tomcat user.
