CVE-2025-62509Network attack vector

Cross-tenant file access via name-based authorization

Published Oct 20, 2025 · Updated Oct 20, 2025

Improper access control in error311 FileRise before 1.4.0 allows remote authenticated users to read, modify, or delete other users' files. File and folder operation endpoints infer ownership and visibility from predictable folder names instead of enforcing per-request read, write, and ownership checks. A non-admin account and a top-level folder whose name matches another user are sufficient to compromise file confidentiality and integrity without interrupting service.
