## Proteus Security Audit Exposes Terminal Injection, CLI Injection, and Privilege Escalation Risks
An internal security audit conducted in May 2026 on the `claude/security-vulnerability-audit-e7Mv1` branch has surfaced multiple findings in the Proteus codebase, ranging from terminal injection to privilege escalation vectors. The audit, which targeted the project's security posture, produced at least eight documented findings ranked by severity, with a high-severity ANSI escape character injection flaw standing as the most critical exposure identified so far.

The highest-rated finding (#224) describes a hostile SSID ANSI escape and control-character injection vulnerability capable of targeting the operator's terminal and journald logs. Closely related, medium-severity finding #225 flags the NetworkManager dispatcher passing an attacker-controlled `$CONNECTION_ID`—derived from the SSID—as a CLI flag value without the standard `--` separator or upstream validation, creating a potential command injection path. Additional medium findings include modulo bias in MAC OUI and prefix pickers that undermines randomization uniformity (#226), missing `#[serde(deny_unknown_fields)]` and numeric-range validation on `Raw*Config` structs (#227), and inconsistent systemd hardening across service units where only `proteus-events.service` follows the strict security template (#228).

Privilege escalation concerns also surfaced. Finding #230 notes that `proteus persona edit` runs the operator's `$EDITOR` as root without the HOME-not-/root warning that `config edit` already displays. A time-of-check-time-of-use (TOCTOU) race condition in `proteus persona import` between validation steps (#231) was also flagged, though the finding entry appears truncated. The consolidated findings are being tracked under a single index issue, with remediation presumably underway. The range and nature of these issues—spanning injection, randomness, hardening, and validation—suggests an expanded attack surface across network handling, configuration parsing, and systemd service execution.
