phi versions 0.1.1 through 0.28.4 have an improper link resolution vulnerability that allows malicious repositories to bypass workspace-only write restrictions. This is due to lexical-only path checks in the permission gate, enabling attackers to commit symbolic links pointing outside the workspace. By combining this with prompt injection, attackers can cause the write tool to write attacker-controlled content to external files without user approval.

Phi versions 0.3.0 through 0.28.4 have a permission bypass vulnerability that allows spawned sub-agents to escape workspace-only write and readonly restrictions. This occurs when an attacker supplies an unchecked working directory to the agent_spawn function, enabling unapproved file writes in locations writable by the user.
