Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-9467 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.vaadin:vaadin-server (Maven): affected from 7.0.0; fixed in 7.7.48\n- com.vaadin:vaadin-server (Maven): affected from 7.0.0; fixed in 7.7.48\n- com.vaadin:vaadin-server (Maven): affected from 8.0.0; fixed in 8.28.2\n- com.vaadin:vaadin-server (Maven): affected from 8.0.0; fixed in 8.28.2\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-2025-9467/ (Markdown: https://insights.sbomify.com/CVE-2025-9467/index.md)","id":"CVE-2025-9467","markdown":"https://insights.sbomify.com/CVE-2025-9467/index.md","name":"CVE-2025-9467","record":{"aliases":["GHSA-9gfh-4fwj-w3rj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Vaadin Java framework","requires_auth":"low_privilege","summary":"Attackers can bypass server-side file upload validation in Vaadin applications using the start listener, potentially uploading malicious files.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Vaadin","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/S:N/AU:N/R:U/V:D/RE:L/U:Green","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"When the Vaadin Upload's start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation. \n\nUsers of affected versions should apply the following mitigation or upgrade.
