CVE-2026-8757Public exploitNetwork attack vector

Unauthenticated directory deletion via unsanitized session identifier

Published May 17, 2026 · Updated May 17, 2026

Path traversal in Aden Hive 0.11.0 and earlier allows remote attackers to delete host directories via a crafted session ID. The DELETE /api/sessions/history/{session_id} handler joins the decoded route value beneath ~/.hive/queen/session without safe_path_segment, then recursively removes the resulting directory with shutil.rmtree(). No authentication or user interaction is required; deletion is limited to directories writable by the Hive process and can destroy data or interrupt service.
