CVE-2026-18903Network attack vector

Authenticated file disclosure via unsanitized image path

Published Aug 5, 2026 · Updated Aug 5, 2026

Path traversal in yeqifu warehouse allows remote authenticated users to read server files through the image-download endpoint. FileController.showImageByPath passes the untrusted path parameter to AppFileUtils.createResponseEntity, which joins it directly to UPLOAD_PATH and reads the resulting File without canonicalization or a containment check. A low-privileged application account and network access to the endpoint are required, and successful traversal discloses files readable by the server process without modifying them.
