Remote profile deletion via unconditional recursive cleanup
Published Aug 6, 2026 · Updated Aug 6, 2026
Incomplete cleanup in Poco-AI Poco 0.5.0 through 0.5.4 allows remote attackers to delete Claude Code profile data through task execution. WorkspaceManager._setup_session_persistence recursively removes a real runtime-user .claude directory and replaces it with a workspace symlink before agent logic runs. The trigger requires a reachable executor API and an existing nonsymlink .claude directory; any accepted task payload permanently removes the stored profile data.
