| Title | YunaiV ruoyi-vue-pro 2026.04-jdk8-SNAPSHOT Arbitrary File Write |
|---|
| Description | A vulnerability has been found in YunaiV ruoyi-vue-pro. The AppFileController file upload endpoint is exposed without authentication through @PermitAll. In local file storage mode, the upload path is built from user-controlled directory and original filename values without proper normalization or traversal checks. As a result, a remote unauthenticated attacker can use path traversal sequences to write uploaded files outside of the configured basePath. Dynamic testing confirmed that files could be written to arbitrary same-drive directories and that frontend assets such as index.html could be overwritten, resulting in persistent cross-site scripting. The issue affects deployments using local file storage.
