CVE-2026-13528Public exploitNetwork attack vector

Unauthenticated arbitrary file write via unnormalized upload paths

Published Jun 29, 2026 · Updated Jun 29, 2026

Path traversal in YunaiV RuoYi-Vue Pro 2026.04-jdk8-SNAPSHOT allows remote attackers to write files outside the upload directory. AppFileController passes an unvalidated directory and original filename to generateUploadPath, which concatenates them before LocalFileClient writes the resulting path. The upload route permits unauthenticated requests, but arbitrary filesystem writes require the Local storage backend; object and remote storage backends are not affected by traversal.
