GitHub Security: Role-Gate Script Vulnerable to Pane Title Manipulation, Risk of Privilege Escalation

A critical security vulnerability has been identified in the `role-gate.ps1` script, where the mechanism fails to protect against attacker-controlled mutation of pane labels or titles. This flaw creates a direct path for privilege escalation. If an agent with initial access can modify the title of its own pane, it could potentially mutate its displayed or assigned role, bypassing intended access controls.

The finding, logged as TASK-027, centers on a missing validation layer. The script's current logic appears to trust client-side or user-modifiable elements—specifically the pane's label or title—as a source of truth for role authorization. This design allows an authenticated user to potentially alter their perceived permissions by changing a simple UI element, rather than having their role immutably bound to a server-verified identity or token.

The required fix points to a fundamental architectural shift: either implementing immutable role binding at the session or connection level, or introducing robust server-side validation that independently verifies a user's role against a trusted authority before granting access. Without this remediation, systems relying on this script for role-based gating are exposed to unauthorized access risks, where lower-privileged users might gain entry to restricted functions or data.
