Miggo AIRoot Cause Analysis

The vulnerability stemmed from missing CSRF protections in state-changing backend actions. The GitHub PR #3123 commits show CSRF checks were added to: analytics reset, blog mass actions, module installation, user restoration, and mailmotor pinging. These functions were vulnerable because they handled privileged operations without verifying request authenticity. The high confidence comes from direct correlation between commit messages adding CSRF checks and the CVE description of authentication hijacking via missing CSRF protections.
