Curator notes
AppOmni Labs (Aaron Costello). Published 2025-11-19. A low-privileged user who can only create tickets plants hidden instructions; a benign agent later reads them and recruits more privileged agents that act with the initiating admin's authority. ServiceNow 'confirmed these behaviors were intended'; this is a configuration/default-posture failure, not a patched bug, which makes it a standing risk rather than a closed one. Root causes cited: insecure LLM selection and default team-based agent grouping.
