Phi 0.3.0 through 0.28.4 contains a permission bypass vulnerability that allows spawned sub-agents to escape workspace_only_writes and readonly mode by supplying an unchecked workdir to agent_spawn. Attackers can plant prompt-injected instructions in processed content so the agent spawns a worker rooted elsewhere, causing unapproved file writes anywhere the user can write.
