Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of GHSA-94g8-xv23-7656 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.vaadin:vaadin-upload-flow (Maven): affected from 2.0.0; fixed in 14.13.1\n- com.vaadin:vaadin-upload-flow (Maven): affected from 2.0.0; fixed in 14.13.1\n- com.vaadin:vaadin-upload-flow (Maven): affected from 23.0.0; fixed in 23.6.2\n- com.vaadin:vaadin-upload-flow (Maven): affected from 23.0.0; fixed in 23.6.2\n- com.vaadin:vaadin-upload-flow (Maven): affected from 24.0.0; fixed in 24.7.7\n- com.vaadin:vaadin-upload-flow (Maven): affected from 24.0.0; fixed in 24.7.7\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/GHSA-94g8-xv23-7656/ (Markdown: https://insights.sbomify.com/GHSA-94g8-xv23-7656/index.md)","id":"GHSA-94g8-xv23-7656","markdown":"https://insights.sbomify.com/GHSA-94g8-xv23-7656/index.md","name":"GHSA-94g8-xv23-7656","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Vaadin Flow Components","requires_auth":"low_privilege","summary":"Attackers can bypass server-side upload validation in Vaadin Flow Components to upload malicious files, requiring an upgrade to fix.","user_interaction":"required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Description\nWhen the Vaadin Upload's start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation.
