Report security vulnerabilities via GitHub Security Advisories.

Critical Rules:

• Never log TELEE_PASSWORD, TELEE_PRIVPASSWORD, or credentials
• Mask secrets in output (show first 4 chars: ${TOKEN:0:4}…)
• Use SSH in documentation (Telnet with explicit warnings)
• No automatic session logging

Safe Example:

export TELEE_USERNAME=admin
export TELEE_PASSWORD='<password>'
telee -H device.example.internal -C "show version" --secure

Unsafe Example:

# DO NOT hardcode credentials
telee -u admin -p password123 -H device.example.internal
