CVE-2026-0522Public exploitNetwork attack vector

Authenticated file disclosure via upload path manipulation

Published Apr 1, 2026 · Updated Apr 1, 2026

Path traversal in VertiGIS FM before 10.11.363 allows remote authenticated users to read arbitrary server files through the upload flow. The upload workflow accepts an attacker-controlled file path and later dereferences that stored path during download instead of binding the request to the uploaded object. A valid login is required; exposure includes application secrets, while UNC-path resolution can trigger outbound NTLM authentication.
