CVE-2025-52904Public exploitNetwork attack vector

Cross-scope file access via unrestricted child processes

Published Jun 26, 2025 · Updated Jun 9, 2026

Improper scope enforcement in File Browser 2.0.0 through 2.33.7 allows remote authenticated users to access files via shell commands. The command runner launches permitted commands as unrestricted child processes under the server UID and never applies the account's file scope. An administrator must enable command execution and grant commands; the user can then read or alter every server-managed file, including account password hashes.
