Is this vulnerability remotely exploitable?

Yes, if the File Browser instance is exposed over the network and an attacker can interact with its web interface or API. Exploitation involves crafting file operations that target directories whose names share prefixes with protected paths.

Does an attacker need authentication to exploit this issue?

In most deployments, practical exploitation requires at least some level of access (e.g., a low-privilege user account) to reach file operations governed by access rules. However, if anonymous or public access is allowed and governed by these rules, then the impact can apply to unauthenticated users as well.

What is the safest general fix pattern?

Replace naive string-based path matching with robust, normalized, segment-aware path comparisons. Ensure that access rules apply only to the exact directory or its descendants by verifying directory boundaries (e.g., using canonical paths and requiring a trailing separator for directories).
