Cross-device command execution via unsigned callback rebinding
Published Jul 27, 2026 · Updated Jul 27, 2026
Authorization bypass in United by AI DroidClaw 0.5.0 through 0.5.3 allows attackers to redirect scheduled goals to another device. The POST /goals/execute handler skips signature verification when QSTASH_CURRENT_SIGNING_KEY is empty and trusts callback deviceId and userId values instead of stored session bindings. A valid scheduled sessionId and an online victim device are required; successful exploitation runs goal-derived commands on the victim phone.
