Vulnerability in pulseaiclub phi

[ Description ]Official description

phi 0.1.1 through 0.28.4 contains an improper link resolution vulnerability that allows malicious repositories to bypass workspace_only_writes by exploiting lexical-only path checks in the permission gate. Attackers can commit symlinks pointing outside the workspace and use prompt injection to make the write tool write attacker-influenced content to external files without approval.
