How the CVE Works
The vulnerability in Filebrowser arises from improper scope enforcement in the Command Execution feature. When shell commands are executed, they run under the server process’s UID without scope restrictions. This allows attackers with command execution privileges to bypass file access controls, accessing all files managed by the server, including the Filebrowser database containing password hashes. Exploiting this flaw requires an account with command execution permissions, but combined with other vulnerabilities (e.g., allowlist bypass), it can lead to full system compromise.
