CHAIN-054 — PIM eligible role activated without approval gate

Summary

Severity: High · Likelihood: Medium · Logic: ALL

Why this chain matters

A high-privilege role (Global Admin, User Access Admin) is assigned Eligible via PIM but the activation policy requires neither an approver nor justification. Any identity that compromises the eligible principal's creds can self-activate to full admin with zero friction.

How the logic works

The chain fires only when every rule above has at least one finding in the current scan. Missing any one rule breaks the chain — so remediating any single step disrupts the attack path.
