Agent Verify

File access with a caller-controlled path

HighAV-RUNTIME-011Runtime safetyCore pack

What it finds

A file is read, written, or deleted using a path taken directly from request, tool, or model input, with no visible check that it stays inside an allowed folder.

Why it matters

A path like ../../.env or /etc/passwd lets an attacker read secrets or overwrite files outside the folder the agent is supposed to use.

What an attacker could do: Could expose configuration files and credentials, or let an attacker overwrite or delete files on the host.

How to fix it

Resolve every path against a fixed base directory and reject it unless the resolved path still starts with that directory. Prefer opaque file IDs over raw paths.

Pro shows the corrected code for your exact file, step by step, and re-scans to confirm the fix. See plans
