CVE-2025-52903Public exploitNetwork attack vector

Authenticated code execution via command-spawning utilities

Published Jun 26, 2025 · Updated Jun 9, 2026

Command injection in File Browser before 2.33.10 allows remote authenticated users to execute code as the server process via its web shell. The allowlist validates only the initial command name, so permitted utilities such as find can launch unlisted programs through their own arguments. An account needs Execute Commands permission, an administrator-enabled feature, and at least one permitted command; execution inherits server-process privileges.
