Why it matters
Composition-based privilege escalation lets AI agents cross security boundaries without any exploit or malfunction, so defenders must review capability combinations rather than individual tool permissions.
Privilege AI publishes a reference explainer on privilege escalation in AI agent systems, arguing that escalation usually arises from composition — individually approved capabilities (e.g. read-confidential plus send-external), confused-deputy identity propagation, delegation chains, and persistent memory — combining into effects no single review considered. The piece offers a review procedure (enumerate effects, cross-check tool pairs, verify identity at each hop) and structural preventions like splitting agents and removing egress paths.
